I'm trying do the following integration: where d >= 0. I try to get an explicit expression and I think the result should be a positive value since the integrand is greater or equal to 0, but...

I think Sympy makes a mistake in calculating the Fourier transform of a trig function. For example: from sympy import fourier_transform, sin from sympy.abc import x, k print fourier_transform(sin(...

I tried the following on SymPy Live b,c,t = symbols('b c t') g = 1/(1+exp(c*(b-t))) integrate(g,t) The result is Integral(1/(exp(c*(b - t)) + 1), t) which I understand as "could not handle this"...
