NCERT Solutions class 12 Maths Chapter 2 Inverse Trigonometric Functions in PDF form to free download. After doing NCERT students should go for Exemplar questions which provide ample practice of the chapters. Before going through this chapter, student should have the knowledge of function and their types, domain, range of a function, Formulae for trigonometric functions of sum, difference, multiple and sub-multiples of angles. Some of these concepts are given in the chapter 1 Relations and Functions. The Previous Years Papers are to know the type and pattern of the questions asked which are designed as per latest CBSE Syllabus for the current academic session. The quick description of the chapter is given below after the PDF solutions and other contents.

Inverse Trigonometric Functions
We know that a function has inverse if and only if it is one – one and onto. There are many functions like trigonometric functions are not one – one or onto because these functions periodic so these are many one. In order to get inverse of these functions, we must restrict their domain and co-domain in such a way that they become one – one and onto and these restricted values are known as principle values.
There are some important theorems/ properties of inverse trigonometric functions. It is important to know that how to convert one function into the terms of others.
Complement functions are useful during the conversion of one functions into it complimentary functions.
During the application of addition formula of tan, we should know that whether the product of x and y is greater than 1 or not. If it is more than 1, use the above formula and then apply the following formula.
The study of trigonometric functions started in 2nd millennium BC but in India it flourished in the Gupta Period due to Aryabhata. During the middle age, the study of trigonometry continued in Islamic Maths. The modern form of trigonometry functions were being used since 17th century by famous mathematician Isaac Newton, James Stirling etc.
