I came across something which i think should have been solved by sympy:
> from sympy import *> x, y, z = symbols('x y z')> n, N = symbols('n N', integer=True)> summation(sin(n*x), (n, 1, N)) Sum(sin(n*x), (n, 1, N)) # so it returns the expression as it is I expected the answer to be a *piece-wise* function, what's the catch in this ? -- You received this message because you are subscribed to the Google Groups "sympy" group.
