**NCERT Solutions for Class 12 Maths Chapter Wise:- **

** NCERT solutions for class 12 maths chapter 1 Relations and Functions : **If two sets of elements are related in some ways, we say these two sets have a relation. Father, mother, sister, brother are real-life examples of relations. Relation becomes function when for every input there is only only one output. For different inputs, the output can be the same. Every function is a relation, but every relation doesn't represent a function. In this chapter, you will learn about types of relations, reflective, transactive and equivalence relation, functions, range, domain and co-domain of function, which have already been introduced in maths of NCERT class 11. In this chapter, there are 4 exercises. Click on the above link to get class 12 NCERT solutions of this chapter.

Also, you are going to study the types, operation transpose and the inverse of the matrix, and properties of matrices which is one of the most powerful tools of mathematics. This tool simplifies our work when compared with other straight forward methods. In NCERT solutions of this chapter there are 4 exercises with 62 questions.

** NCERT solution for class 12 maths chapter 4 Determinants : **In the previous chapter you have already learnt matrices and its properties. For every square matrix, you can compute a number called "Determinant". It shows the factor by which times area or volume of linear transformation has changed. In class 12 NCERT maths solutions for this chapter, you will learn about the determinants of a square matrix, and properties of determinant, consistency, inconsistency, the number of solutions of linear equations and solving system of linear equations which is an important part of matrices. So, we are dealing with determinants of order up to three only. In this chapter, there are 6 exercises.

** NCERT solutions for class 12 maths chapter 5 Continuity and Differentiability : **In the class 11 NCERT you have learnt about the differentiation of certain functions. In class 12 NCERT solutions for this chapter, you will learn about differentiability, continuity and how differentiability is related to continuity. The important concepts that you will study are continuity, differentiability, the derivative of a composite function, a derivative of a trigonometric function, the derivative of the inverse trigonometric functions, derivative of the logarithm, the derivative of the exponential function, chain rule, role's theorem, and Lagrange mean value theorem, etc. In this chapter, there are a total of eight exercises.

** NCERT solutions for class 12 maths chapter 7 Integrals : **Differential calculus is centered around the concept of differentiation, defining tangent and calculating the slope of the line. Integral calculus is centered around defining and calculating the area of the region bounded by the graph of a function. Integration means 'bringing-together' which is the inverse process of differentiation(Set-apart). The function is integrable only if the function is already differentiated. Remember every function is not integrable means you can't integrate every function. In this chapter, you will learn about the integrals of various functions and also discuss its application like calculation of areas under the graphs. There are 11 exercises in this chapter.
