AHL 3.9
The inverse of sin is arcsin, also written sin−1. Its domain is the range of sin: (−1,1), and its range is the domain of sinx, restricted so that the inverse function passes the vertical line test: (−2π,2π).
The graph of y=arcsinx is the mirror image of sinx (restricted to −2π<x<2π) in the line y=x, giving an increasing function:
