[Bug]XCAS can't solve this equation - yangyongkang - 07-30-2019 03:39 AM I am coming again, talk nonsense, paste the code. Code: solve([c=e^a*cos(b),d=e^a*sin(b)],[a,b]) RE: [Bug]XCAS can't solve this equation - parisse - 07-30-2019 10:28 AM 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. |
