What is Variation? | Types of Variation – Direct, Inverse, Joint, Combined, Partial Variation

What is Variation

Variation can be clearly understood if you know about Variables. In Mathematics, we generally deal with two types of quantities namely variables and constants. If the value of a quantity remains unchanged during different scenarios then it is said to be constant. On the other hand, if the value of a quantity changes under varying conditions then it is said to be a variable. Refer to the complete article to know about the Definition of Variation, Types of Variation, and Solved Examples on Variation, etc.

What is Variation?

In Mathematical Equations when a relationship is established there exist two types of quantities one is constant and the other is variable. Constant will not alter with the change in other parameters of the equation and the other is a variable that changes with different situations. The Changing of variable parameters is called a Variation.

You can understand the concept of variation with a simple equation y = mx

Here m is the constant and if we consider m = 2 then y becomes 2x

If x = 1, then y becomes y = 2*1 = 2

If x = 2, then y becomes y = 2*2 = 4

By changing the value of y, x gets different values. This is the variation of y with different values of x and similarly, you can get different values of y if the value of x changes.

Types of Variation

Variations can be of different types according to the pattern of changing or relationships of variables. We have explained the most common types of variation here and they are as follows

Direct Variation: If variables change proportionately i.e. either decrease or increase then it is said to be a direct variation. If A is in direct variation with B then it can be symbolically written as A α B.

Indirect Variation: In the case of Indirect or Inverse Variation variables change disproportionately i.e. when one variable increases the other one decreases. The behavior of Variables is exactly the opposite of direct variation. Thus, it is called an Indirect or Inverse Variation. If A is in indirect variation with B then it is symbolically written as A α \(\frac { 1 }{ B } \)

Joint Variation: If Two or more variables are related directly or one variable change with change product of two or more variables then it is said to be a Joint Variation. If A is in joint variation with B and C then it is symbolically represented as such A α BC

Combined Variation: Combined Variation is a combination of direct, indirect, or joint variation. In this kind of variation, three or more variables exist. If A is in combination with B, C then it can be symbolically represented as A α \(\frac { B }{ C } \) or A α \(\frac { C }{ B } \)

Partial Variation: If two variables are related using a formula or a variable is related by the sum of two or more variables then it is said to be a Partial Variation. y = mx+c is a straight line equation and is an example of Partial Variation.

FAQs on Variation

1. How do you define Variation?

Changing of Variable Parameters is called a Variation.

2. What are the Types of Variation?

There are different types of variation and they are as follows

  • Direct Variation
  • Indirect Variation
  • Joint Variation
  • Combined Variation
  • Partial Variation

3. What is a direct variation proportion?

A Relations is said to be in direct variation when one variable changes and the second variable changes proportionally.

Subsets – Definition, Symbol, Formula, Types, Properties and Examples

Subset

Subsets fall under the mathematics concept Sets. A Set is a collection of objects or elements enclosed within curly braces {}. If Set A is a Collection of Odd Numbers and Set B includes { 1, 3, 5} then B is said to be a subset of A and is denoted by B⊆A whereas A is the Superset of B.

Elements of Set can be anything such as variables, constants, real numbers, whole numbers, etc. It can include a null set too at times. Learn about Subsets Definition, Symbol, Formula, Types, and Examples in the later modules.

What is a Subset?

Set A is said to be a subset of Set B if all the elements present in Set A are also present in Set B. In other words, we can say Set A is contained within Set B.

Example:  If Set A has {a, b} and set B has {a, b, c}, then A is the subset of B because elements of A are also present in set B.

Subset Symbol

In Set theory, the Subset is denoted by the symbol ⊆ and is usually read as the Subset of. Using the symbol let us denote the subsets as follows

A ⊆ B; which denotes Set A is a subset of Set B.

Remember a Subset may include all the elements that are present in the Set.

Also, Read:

All Subsets of a Set

Subsets of any set consist of all possible sets including its elements and even null set. Let us provide you an example and provide the possible combinations of a set so that you can better understand.

Example:

What are the Subsets of Set A = {5, 6, 7, 8}?

Solution:

Given Set A = {5, 6, 7, 8}

Subsets include

{}

{5}, {6}, {7}, {8},

{5,6}, {5, 7}, {5,8}, {6,7},{6,8}, {7,8},

{5,6,7}, {6,7,8}, {5,7,8}, {5,6,8}

{5,6,7,8}

Types of Subsets

Subsets are Classified into two types namely

  • Proper subsets
  • Improper subsets

Proper Subsets: Proper Set includes only a few elements of the original set.

Improper Subsets: Improper Set includes all the elements of the original set along with the null set.

Example:

If set A = { 4, 6, 8}, then,

Number of subsets: {4}, {6}, {8}, {4,6}, {6,8}, {4,8}, {4,6,8} and Φ or {}.

Proper Subsets: {}, {4}, {6}, {8}, {4,6}, {6,8}, {4,8}

Improper Subset: {4,6,8}

There is no proper formula to find how many subsets are there. You just need to write each one of them and distinguish whether it is a proper subset or improper subset.

What are Proper Subsets?

Set A is said to be a Proper Subset of Set B if Set B has at least one element that doesn’t exist in Set A.

Example: If Set A has elements as {4, 6} and set B has elements as {4, 6, 16}, then Set A is the Proper Subset of B because 16 is not present in the set A.

Proper Subset Symbol

A Proper Subset is represented by the symbol ⊂ and is read as “Proper Subset of”. Using this symbol we can denote the Proper Subset for Set A and Set B as A ⊂ B.

Proper Subset Formula

If we have to pick the “n” number of elements from a set containing the “N” number of elements you can do so in NCn number of ways.

How many Subsets and Proper Subsets does a Set have?

If a Set has “n” elements then there are 2n subsets for the given set and there are 2n -1 proper subsets for the given set.

Consider an example, If set X has the elements, X = {x, y}, then the proper subset of the given subset are { }, {x}, and {y}.

Here, the number of elements in the set is 2.

We know that the formula to calculate the number of proper subsets is 2n – 1.

= 22 – 1

= 4 – 1

= 3

Thus, the number of proper subset for the given set is 3 ({ }, {x}, {y}).

What are Improper Subsets?

A Subset that contains all the elements of the original set are called Improper Sets. It is represented using the symbol ⊆.

Set A ={1,2,3} Then, the subsets of A are;

{}, {1}, {2}, {3}, {1,2}, {2,3}, {1,3} and {1,2,3}.

Where, {}, {1}, {2}, {3}, {1,2}, {2,3}, {1,3} are the proper subsets and {1,2,3} is the improper subsets. Therefore, we can write {1,2,3} ⊆ A.

Note: Empty Set is an Improper Subset of itself and is a Proper Subset of any other set.

Power Set

Power Set is said to be a collection of all subsets. It is denoted by P(A).

If Set A has elements {a, b} then the Power Set of A is

P(A) = {∅, {a}, {b}, {a, b}}

Properties of Subsets

Below is the list of Some of the Important Properties of Subsets and they are as such

  • Every Set is a subset of the given set itself. It means A ⊂ A or B ⊂ B, etc.
  • Empty Set is a Subset of Every Set.
  • If A is a Subset of B it means A is contained within B.
  • If Set A is a subset of Set B then we can infer that B is a superset of A.

Subsets Example Problems

1. How many subsets containing three elements can be formed from the set?

S = { 1, 2, 3, 4, 5, 6, 7 }

Solution:

No. of Elements in the Set = 7

No. of Elements in the Subset = 3

No. of Possible Elements containing the 3 Elements is 7C3

=\(\frac { 7! }{ (7-3)!*3! } \)

= \(\frac { 7*6*5*4! }{ 4!*3! } \)

= 35

2. Find the number of subsets and the number of proper subsets for the given set A = {4, 5, 6, 7,8}?

Solution:

Given: A = {4, 5, 6, 7,8}

The number of elements in the set is 4

We know that,

The formula to calculate the number of subsets of a given set is 2n

= 25 = 32

The number of subsets is 32

The formula to calculate the number of proper subsets of a given set is 2n – 1

= 25 – 1

= 32 – 1 = 31

The number of proper subsets is 31.

FAQs on Subsets

1. What are Types of Subsets?

Subsets are classified into two types and they are as follows

Intersection of Sets – Definition, Symbol, Properties & Solved Examples

Intersection of Sets - Definition, Symbol, Properties & Solved Examples on Intersection of Sets

In Set theory, there are various types of set operations like Subsets, Difference of sets, Union of sets, Complement of sets, and Intersections of sets. Students can easily understand and learn the set theory concepts by referring to our articles. So, today we have come up with the Intersection of Sets topic. Let’s go through this page and learn about the intersection of sets definition, symbol, properties, and examples.

Intersection of Sets Definition

If the Intersection of two sets A and B, then it is denoted by A∩B, where it contains all the elements which are common to both A and B. The symbol to denote the intersection of sets is ‘∩’. All those elements that relate to both A and B denote the intersection of A and B. Hence, we can say that,
A ∩ B = {x : x ∈ A and x ∈ B}

For n sets A1, A2, A3,……A n where all these sets are the subset of Universal set (set U). The definition of the intersection is the set of all elements which are common to all these n sets.

What is the Intersection of Two Sets?

If there are two sets, Set A and Set B, then the intersection of sets is given by:

A∩B = n(A) + n(B) – n(A∪B), where

n(A) is the cardinal number of set A,
n(B) is the cardinal number of set B,
n(A∪B) is the cardinal number of a union of two sets ie., A and B.

For Example: The intersection of two sets ie., A = {1, 2, 3} and B = {2, 3, 4} then find A∩B?

We know, A∩B = n(A) + n(B) – n(A∪B)

After calculating the process of the intersection of two sets, the result is like this A∩B = {2, 3}.

Properties of Intersection of a Set

i) Commutative Law: The union of two sets A and B follow the commutative law i.e., A ∩ B = B ∩ A

ii) Associative Law: The intersection operation follows the associative law i.e., If we have three sets A, B, and C then, (A ∩ B) ∩ C = A ∩ (B ∩ C)

iii) Identity Law: The intersection of an empty set with any set A gives the empty set itself i.e., A ∩ ∅ = ∅

iv) Idempotent Law: The intersection of any set A with itself gives the set A i.e., A ∩ A = A

v) Law of U: The intersection of a universal set U with its subset A gives the set A itself. A ∩ U = A

vi) Distributive Law: According to this law: A ∩ (B ∪ C) = ( A ∩ B ) ∪ (A ∩ C)

Solved Examples on Intersection of Sets

1. Let U be the universal set consisting of all the n – sided regular polygons where 5 ≤ n ≤ 9. If set A, B, and C are defined as:

A = {pentagon, hexagon, octagon}

B = {pentagon, hexagon, nonagon, heptagon}

C = {nonagon}

Find the intersection of the sets A and B

Solution:

Given Universal Set U = {pentagon , hexagon , heptagon , octagon , nonagon}, A = {pentagon, hexagon, octagon}, B = {pentagon, hexagon, nonagon, heptagon}, C = {nonagon}

Now, calculate the intersection of sets A and B

Here, the intersection of sets means the common elements consist in both A and B:

The elements of A = {pentagon, hexagon, octagon}, and B = {pentagon, hexagon, nonagon, heptagon}

Then, A ∩ B = {pentagon, hexagon}.

2. If A = {1,3,5,7,9} and B = {2,3,5,6,8}. Find intersection of two set A and B.

Solution:

Given Set A = {1,3,5,7,9} and Set B = {2,3,5,6,8}

Here 3, 5 are the common elements in both A and B sets.

So, the intersection of two sets A and B are, A ∩ B = {3, 5}.

3. If P = {x, y, z} and Q = {ф}. Find the intersection of two given sets P and Q.

Solution:

Given sets are P = {x, y, z} and Q = {ф}

The Intersection of given sets P ∩ Q = { }.

Signed Magnitude Representation of Binary Numbers with Examples | How to Represent Sign Magnitude Form?

Signed Magnitude Representation

In mathematics, every number has a sign. Negative numbers with any base are denoted by a prefix symbol ‘-‘. Binary numbers are the numbers that are expressed in base 2 having two symbols 0 and 1. Generally, the computer uses binary numbers. The sign of numbers in binary form is represented by the first binary digit in the number. Get the definition of signed magnitude representation and convert binary numbers into decimal and solved examples in the below sections. You can also find the difference between signed binary numbers and two’s complement numbers on this page.

Signed Magnitude Representation – Introduction

Every 8-bit binary number has magnitude and symbol which is used to indicate either the magnitude is positive or negative. The symbol defines the magnitude of the number. The sign bit is the left-most bit in the binary number. It is also known as the most significant bit. If the sign bit is 1, then it is a negative number, if the sign bit is 0, then it is a positive number.

The 8-bit binary numbers range from -127 to +127. To know the magnitude of the binary number, convert it into a decimal by following the below-mentioned rules and guidelines.

How to Convert Binary Numbers to Decimal Numbers?

Follow the below-listed steps to convert from a binary number to a decimal number. They are along the lines

  • Let us take any 8-bit binary number.
  • By checking the MSB digit, identify whether the number is positive or negative.
  • Now, take the remaining 7 digits into consideration.
  • Write the number 2 to the power 0 to n from the right side

Example 4:

(10010000)2

Solution:

Given binary number is (10010000)2

The most significant digit is 1. So, the sign is negative.

The decimal form of the number = 26 x 0 + 25 x 0 + 24 x 1 + 23 x 0 + 22 x 0 + 21 x 0 + 20 x 0

= 64 x 0 + 32 x 0 + 16 x 1 + 8 x 0 + 4 x 0 + 2 x 0 + 1 x 0

= 0 + 0 + 16 + 0 + 0 + 0 + 0

= 16

Therefore, (10010000) = -(16)10

FAQs on Signed Magnitude Representation

Multiplication of Fractions steps and methods are here. Check rules, tricks, and tips to solve fraction multiplication problems. Refer to the important formulae and also types involved in it. Know the fraction multiplication solved examples, types, and parts of fractions, variables, etc. Go through the below sections to get the complete details regarding multiplication methods, formulae, rules, etc.

Multiplication of Fractions – Introduction

Fractions multiplication starts with numerators multiplication followed by denominators multiplication. The resultant fraction of the multiplication fraction can be simplified further and can be reduced to its lowest terms. Fraction Multiplication is not the same as adding or subtracting the fraction values.

Any two or more fractions with different denominators can easily be multiplied. The main thing to be considered is the fractions should not be mixed fractions, they should be either proper or improper fractions. There are various steps involved in multiplying the fractions. They are:

  1. In the fractions multiplication, we multiply the numerator with the numerator term to get the desired result of the numerator.
  2.  In the fractions multiplication, we multiply the denominator with the denominator term to get the desired result of the denominator.
  3. After finding the resultant numerator and denominator values, check for simplification if possible
  4. Once the simplification is done, we get the final resultant value.

How to Multiply Mixed Fractions?

Consider a mixed fraction which is the form of a \(\frac { b }{ c } \).

In the above-mixed fraction, convert the fraction value into an improper fraction. After converting it into an improper fraction, apply all the above steps we do in the multiplication of fractions. To convert mixed fractions into improper fractions, we apply the following steps:

  • Multiply the whole number (a) with the denominator (c). We get the result value (a * c)
  • To the above result value (a * c), add the numerator value (b). After the addition of the numerator, we find the numerator of the improper fraction.
  • The denominator value of the improper fraction will be the denominator of the same mixed fraction.
  • Generally, we can write it as a \(\frac { b }{ c } \) = \(\frac { c*a + b}{ c } \)

Multiplication of Proper Fractions

Multiplication of proper fractions is the easiest form of all the fractions multiplication.

Example:

Solve the equation \(\frac { 2 }{ 3 } \) × \(\frac { 4 }{ 6 } \)?

Solution:

As given in the question,

The equation is \(\frac { 2 }{ 3 } \) × \(\frac { 4 }{ 6 } \)

Here, \(\frac { 2 }{ 3 } \), \(\frac { 4 }{ 6 } \) are the proper fractions. To multiply the proper fractions, we have to follow the steps.

Step 1: First of all, multiply the numerators together i.e., 2 and 4. The solution is 2 * 4 = 8

Step 2: Next, multiply the denominators together ie., 3 and 6. The solution is 3 * 6 = 18. The fraction value can be written as \(\frac { 2*4 }{ 3*6 } \) = \(\frac { 8 }{ 18 } \)

Step 3: Check if you can simplify the resultant equation. On simplification, we can write it as \(\frac { 4 }{ 9 } \)

Multiplication of Improper Fractions

An improper fraction is the one that has a greater denominator than the numerator. If we multiply an improper fraction, we result in an improper fraction.

Example: 

Solve the equation \(\frac { 3 }{ 2 } \) × \(\frac { 7 }{ 5 } \) of the improper fractions?

Solution:

As given in the question,

The equation is \(\frac { 3 }{ 2 } \) × \(\frac { 7 }{ 5 } \)

Here, \(\frac { 3 }{ 2 } \), \(\frac { 7 }{ 5 } \) are improper fractions. To multiply the improper fractions, we have to follow the steps.

Step 1: First of all, multiply the numerators together i.e., 3 and 7. The solution is 3 * 7 = 21

Step 2: Next, multiply the denominators together i.e., 2 and 5. The solution is 2 * 5 = 10. The fraction value can be written as \(\frac { 3*7 }{ 2*5 } \) = \(\frac { 21 }{ 10 } \)

Step 3: Check if you can simplify the resultant equation. In the above equation, simplification is not possible.

Step 4: Now, convert the fraction into an improper fraction. Hence, the result is 2[/latex] = \(\frac { 1 }{ 10 } \)

Multiplication of Mixed Fractions

Mixed Fractions are those fractions which have a whole number and a fraction like 2 [/latex] = \(\frac { 1 }{ 2 } \). When multiplying both the mixed fractions, we have to convert the mixed fractions into improper fractions.

Example:

Multiply the fractions 2\(\frac { 2 }{ 3 } \) and 3\(\frac { 1 }{ 4 } \)

Solution:

The given equation is 2\(\frac { 2 }{ 3 } \) x 3\(\frac { 1 }{ 4 } \)

Here, 2\(\frac { 2 }{ 3 } \) and 3\(\frac { 1 }{ 4 } \) are mixed fractions. To multiply the mixed fractions, we have to follow the following steps.

Step 1: First of all, convert the mixed fractions to improper fractions. To convert the mixed fraction of 2\(\frac { 2 }{ 3 } \), we write it as \(\frac { (3×2+2) }{ 3 } \). The result is 8/3. To convert the mixed fraction of 3\(\frac { 1 }{ 4 } \), we write it as \(\frac { (4×3+1) }{ 4 } \). The result is 13/4

Step 2: Multiply the numerators together i.e., 8 and 13. The solution is 8 * 13 = 104

Step 3: Next, multiply the denominators together i.e., 3 and 4. The solution is 3 * 4 = 12. The fraction value can be written as \(\frac { 8*13 }{ 3*4 } \) = \(\frac { 104 }{ 12 } \)

Step 4: Check if you can simplify the resultant equation. In the above equation, the simplification can be done as \(\frac { 26 }{3 } \).

Step 5: Now, convert the fraction into an improper fraction. Hence the result is 8\(\frac { 2 }{ 3 } \)

No of students involved in fall activity = \(\frac { 2 }{ 3 } \)

To find the fraction of students involved in a fall activity, we have to apply the multiplication of fractions

Hence \(\frac { 2 }{ 3 } \) x \(\frac { 4 }{ 5 } \) = \(\frac { 8 }{ 15 } \)

Thus, \(\frac { 8 }{ 15 } \) fraction of students are involved in a fall activity.

Therefore, the final solution is \(\frac { 8 }{ 15 } \)

Problem 3:

Jimmy has a collection of 18 video games. Of the 18 video games. \(\frac { 1 }{ 3 } \) are sports games. How many of his games are sports games?

Solution:

As given in the question,

No of video games = 18

Part of sports games = \(\frac { 1 }{ 3 } \)

To find the no of sports games, we apply multiplication of fractions

Hence \(\frac { 1 }{ 3 } \) x \(\frac { 18 }{ 1 } \)

=\(\frac { 18 }{ 3 } \)

On further simplications, we get the result as 6.

Therefore, Jimmy has a collection of 6 sports games.
