The word "simplify" is ambiguous but I assume from your examples that what you want is to rewrite powers as exponentials if possible. If so that can be done with e.rewrite(exp): >>> from sympy import * >>> i = I >>> a = i**(-2*i), (-i)**(-2*i), ((-sqrt(3) - i)/2)**(-2*i), ((sqrt(3) - >>> i)/2)**(-2*i) >>> [ai.rewrite(exp) for ai in a] [exp(pi), exp(-pi), exp(-5*pi/3), exp(-pi/3)] -- Oscar -- You received this message because you are subscribed to the Google Groups "sympy" group.
