Complex Integration

[Helge Gabert]

Definite integration in Home doesn't seem to accept complex-valued integrands, nor integrals with complex limits, e.g.,

\int (0, 2*pi, sin(X)*e^(X*i) dX) results in error - invalid input, and \int (-pi-i,pi+i, sin(X)*e^(X*i) dX) returns the same error message. Why is that? Needless to say, Complex is checked in Home settings.

However, no problems in CAS, returning i*pi, and (e^4-4*e^2-1)/(4*e^2)+i*pi, respectively.

Hmm... that is strange. I would not have expected that. It is on the list for investigation. Thank you.

Could be a remnant from the 39Gii. My 42S, with otherwise straightforward complex number support, also won't integrate complex-valued functions.
