Inverse Trigonometric Functions

In this post we discuss about Inverse Trigonometric Functions and also their domain and range. We denote and define Inverse Trigonometric Functions

as follows

Formulas

y=Sin-1x $-\frac{\pi}{2}&space;\leq&space;y&space;\leq&space;\frac{\pi}{2}&space;,&space;-1\leq&space;x&space;\leq&space;1$
y=Cos-1x  $0&space;\leq&space;y&space;\leq&space;\pi&space;,&space;-1&space;\leq&space;x&space;\leq&space;1$
y=Tan-1x  $-\frac{\pi}{2}&space;<&space;y&space;<&space;\frac{\pi}{2}&space;,&space;-\infty&space;<&space;x&space;<&space;\infty$
