NCERT Solutions for Class 12 Maths Chapter 2 – Inverse Trigonometric Functions
October 17, 2020
Chapter 2 of NCERT Class 12 Maths Inverse Trigonometric Functions plays an important role in calculus. Students must practice calculus part of class 12 to score excellent marks in the board exams. NCERT solutions provide solutions for all the problems from chapter 2 of class 12 inverse trigonometric functions. Students can download NCERT solutions PDF of class 12 inverse trigonometric functions, and practice for themselves at any instant of time. The concepts of Inverse trigonometry functions are also used in the higher classes in the streams of science and engineering.
Practicing calculus is very useful to score more marks because the calculus part has more weightage in the board exams as well as many competitive exams. For most of the competitive exams, the questions are given from the topics picked from the NCERT books. NCERT solutions are very clear and easy to understand for the students. Any problem from the Inverse Trigonometric Functions of NCERT Class 12 Maths can be checked from the PDF below if you got stuck anywhere in between solving problems.

Inverse trigonometric functions Definition:
Inverse trigonometric functions also called as “anti-trigonometric” functions are nothing but the inverses of the basic trigonometric functions (i.e. sine, cosine, tangent, cotangent, secant, and cosecant) with suitable restricted domains.
Inverse trigonometric functions Notation
The range of the function is the set of outputs that can be generated by inputting the numbers from the domain into the function and perform the function operation. Range can also be the all real possible numbers(unlimited).
The domain of a function is the set of possible values of the independent variable or variables of that function.
Principal value branch:
Not even one inverse trigonometric function is one to one, Therefore, the ranges of the inverse functions are proper subsets of the domains of the original functions. when one function is desired to one value then the function may be restricted to its principal branch. With this restriction, the inverse of the sine function will evaluate to a single value, which is called the principal value.
The below-given table gives the principal value branches of the inverse trigonometric functions along with their domains and ranges.
