NCERT Solutions for Class 8 Maths Chapter 2 LINEAR EQUATIONS IN ONE VARIABLE in English Medium as well as Hindi Medium updated for new academic session 2021-2022 based on latest NCERT Books for new session.
Introduction
Mathematics has been taught since childhood. Our teachers had laid a good foundation in basic concepts. Through our school education, we acquire knowledge that is necessary to make life successful. It is important to recognise how we can make our personal and professional life better by knowing mathematics.
However, there is a change in school education, which might affect the outcome of your maths education. It is important to know what this change is, and its implication. Here we have taken up the two important problems of mathematics education that impact our understanding of the subject. The first one is the change in textbooks published by NCERT, and the second one is the change in NCERT exam papers.

Introduction
What is a variable? A variable is an element of a set of objects that have a certain property or characteristic. For example, a number is a variable because it can be one, zero, two, three or four. Any member of a set of the same kind is called a “set variable”. A variable in a set can have multiple properties.
A number might have the property that it is divisible by one, another might have the property that it is one less than the number itself, another might have the property that it is one greater than the number. Calculus is the study of differences between two objects of the same kind. The simplest example of a difference is a larger object above a smaller object. Suppose that the bigger object is above the smaller object.

This chapter also includes a separate chapter on Convex functions and Partial Differential Equations. In both cases, much of the book is spent explaining differential equations. Linear Equations Both the categories of differential equations introduced here, namely, ordinary differential equations and partial differential equations,
must be solved using computer programs. However, the chapter dedicated to the latter type of differential equations is very well-illustrated and easy to understand, while the corresponding problems are less abstract. At a high level, differential equations consist of the following: Function: A set of values, called derivatives, a point on that function and a variable, called the parameters.

Introduction
• One Variable in Mathematics • Classes 7 to 9 Inclusive of One Variable Class 6 Updates • One Variable Class 8 There are various methods to solve the linear equations using SDE and similar methods based on different methods. Here, we would be using different methods depending on the nature of the problem for solving linear equations.
The Indian textbooks and teaching methodology do not provide any non-linear programming (NLP) techniques and there is a dire need to introduce NLP in the curriculum. NLP can be used for solving the non-linear programming problems in Physics, Chemistry, Biology and any other subjects. There are five non-linear programming problems.

Introduction
In the two years to be completed by 31 March 2022, 1,37,596 students of Classes 7 and 8 (including those admitted through NEET) will be appearing for the Central Board of Secondary Education (CBSE) Class X exam. These students will be writing math examinations in two languages, English and Hindi,
and one language in which all the combinations are allowed: Arithmetic (i.e., without the use of calculators or Computer Based Tests or any other calculators), and the other language being arithmetic. Therefore, a total of 2,46,675 students of Class 8 are expected to be writing the math examination in 2023-24. It is advisable to get an idea of what the students will be learning from the examination paper.

The formula for the slope of a line
and the same goes for algebraic expressions like the equations for right angle, horizontal and vertical ranges, parallels, angles of tangents, slope of a line and their derivatives. SO WHAT IS THE GENDER GAP ? Other than fundamental issues, there have been several instances of girls being disadvantaged in fields that have been traditionally male dominated.
For example, in sports, while girls are better than boys in certain sports such as swimming and golf, there are others in which they excel less. There have also been instances of girls excelling in individual sports like basketball and badminton but not playing teams sports because they are not considered as strong players.
The formula for the y-intercept
HOWEVER, when the y-intercept is written out, you get a fractional value. This is because the length of the "x-axis" varies with each value of x. Hence, the "y-intercept" takes up a fractional value. This y-intercept is very important and the total must always have the fractional value so that 1/n is still expressed as a negative number even though it has a non-negative "y-intercept". Thus, instead of trying to write out the number, you should just write 1/n which is one of the most simple form of writing 1/n.
What do the slope and y-intercept tell us about a line?
Given a line a and a point b on it, the slope of a line can be described as follows: S = a cos b (3) With this information in hand, we can write a function S that will do the job. This function can take as input a point b, a line a and a function f : S’(f(a)) = f(a) – S’(f(b)). An important rule of computation is that you should divide a line by its derivative: ∫ a b f ( a ) d a = ( 1 – f ( a ) ) 1 / ( 1 + f ( a ) ) d b. Note that this rule is also known as the Pythagorean Theorem.
If a line is straight, i.e. if we know the slope of it (cosine of its angle), then if we know its second derivative (the slope of the line divided by its angle) and the first derivative of the line then S’(f(a)) = f(a) – S’(f(b)). Let’s try to understand the derivation above.
Conclusion
I will submit the final part tomorrow and hope you enjoyed reading this series as much as I did writing it.
