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

Function	Formulas
y=Sin^-1x	$-\frac{\pi}{2} \leq y \leq \frac{\pi}{2} , -1\leq x \leq 1$
y=Cos^-1x	$0 \leq y \leq \pi , -1 \leq x \leq 1$
y=Tan^-1x	$-\frac{\pi}{2} < y < \frac{\pi}{2} , -\infty < x < \infty$
