- To find the inverse of sin, you need to restrict the domain to $[-\frac{\pi}{2}]
- To find the inverse of sin, you need to restrict the domain to $[-\frac{\pi}{2}, \frac{\pi}{2}]$
- To find the inverse of cos, you need to restrict the domain to $[0, \pi]$
- To find the inverse of tangent, you need to restrict the domain to $(-\frac{\pi}{2}, \frac{\pi}{2})$.
