[Bug]XCAS can't solve this equation
I am coming again, talk nonsense, paste the code.
Code: solve([c=e^a*cos(b),d=e^a*sin(b)],[a,b]) study hard, improve every day

RE: [Bug]XCAS can't solve this equation
This is *not* a bug, solve performs *polynomial* system solving, and your system is not polynomial. It's not hard to make it polynomial, replace exp(a) by a and run halftan.
