I get this error message: TypeError: ECL says: Memory limit reached. Please jump to an outer pointer, quit program and enlarge the memory limits before executing the program again.  I know the equation is big but i didn't expected such many problems. I've already tried sympy but nothing. Is there another way? 2019-06-07 01:56:54 +0200 asked a question problem: sage is not able to find solution to an equation.
