The function $\mathrm{arcsin} \colon \mathbb{C} \setminus \left\{ (-\infty,-1) \bigcup (1,\infty) \right\} \rightarrow \mathbb{C}$ is defined by
$$\rm{arcsin}(z)=-i \log \left( iz + \sqrt{1-z^2} \right),$$
where $i$ denotes the imaginary number and $\log$ denotes the logarithm.
Graph of $\mathrm{arcsin}$ on $[-1,1]$.
