RD Sharma Solutions for Class 12 Maths Chapter 4 Inverse Trigonometric Functions

The inverse trigonometric functions do the same thing as the inverse trigonometric relations. Still, when an inverse function is used, because of its restricted range, it only gives one output per input  whichever angle lies within its range. Inverse Trigonometric Functions plays a vital role in calculus to find the various integrals. Specifically, they are the inverses of the sine, cosine, tangent, cotangent, secant, and cosecant functions, and are used to obtain an angle from any of the angle's trigonometric ratios. The idea is the same in trigonometry. Inverse trig functions do the opposite of the "regular" trig functions. For example, Inverse sine (sin - 1) (\sin^{-1}) (sin- 1) left parenthesis, sine, start superscript, minus, 1, end superscript, right parenthesis does the opposite of the sine.
