You could add arctan to the community wiki and add a comment that the other two functions are not built-in

provide custom `arctan` instead of relying on built-in `arctan` function

Can't test, but would something like this work? arcsin := arctan(x / sqrt(1 − sqr(x))); (see en.wikipedia.org/wiki/…)

@bsoelch Not only do I (from a software engineering point of view) dislike reimplementing built-in functionality, but doesn’t this amount to a penalty? You know, I cannot add “Pascal” to the community wiki post, because only arctan is a built-in function.

@bsoelch Certainly I can, but wouldn’t this defeat the purpose of code-golf? There is no benefit in defining a custom arctan anyway: the built-in trigonometric functions (sin, cos, and arctan) can take and output complex numbers.

can you also add a non built-in solution for the arctan function
