If we look up ArcCosh in Mathematica’s documentation, it says “ArcCosh[z] has a branch cut discontinuity in the complex z plane running from −∞ to +1.” But what about values of x that lie on the branch cut? For example, we looked at ArcCosh[-2] above. We can extend arccosh to the entire complex plane, but we cannot extend it as an analytic function.
