I've done a lot of them for fun. I stopped at about 230 - the highest number then was around 310. The list is now 450+.
You need to know some number theory and have a compiler or other access to a bignum library - perl, numpy, C, fortran. I used GNU C with GMP on Cygwin.
I second the idea: do not post solutions elsewhere. You are not helping anyone by doing that.

cacos(3M) cacos(3M)
NAME
cacos, cacosf, cacosl - complex arc cosine functions
SYNOPSIS
cc [ flag... ] file... -lm [ library... ]
#include <complex.h>
double complex cacos(double complex z);
float complex cacosf(float complex z);
long double complex cacosl(long double complex z);
These functions compute the complex arc cosine of z, with branch cuts outside the interval [ -1, +1 ] along the real axis.
These functions return the complex arc cosine value, in the range of a strip mathematically unbounded along the imaginary axis and in the
interval [ 0, pi ] along the real axis.
No errors are defined.
