Inverse Trigonometric Functions

Inverse Trigonometric Functions

Inverse trigonometric functions are used to find the angle that corresponds to a given trigonometric value.

• $\arcsin(x)$ or $\sin^{-1}(x)$: Returns angle in $[-\pi/2, \pi/2]$.
• $\arccos(x)$ or $\cos^{-1}(x)$: Returns angle in $[0, \pi]$.
• $\arctan(x)$ or $\tan^{-1}(x)$: Returns angle in $(-\pi/2, \pi/2)$.
