The process of defining the square root function for all complex numbers is analogous to the process of defining arccosh. First, we define square root to be what we expect for positive real numbers. Then we make a branch cut, in this case (−∞, 0]. Then we define it by analytic continuation for all values not on the cut. Then finally, we define it along the cut by continuity, taking the limit from above.
