I feel ashamed asking this, but how do you take the integral of a complex or pure imaginary function?(adsbygoogle = window.adsbygoogle || []).push({});

My sheer guess is that you take the real parts of the function and integrate them seperately, then take the imaginary part and integrate it, but I don't quite know how to do that last part.

Also, can the definite integral of a complex or imaginary function ever be a real number? Does any function have a derivative or integral of i? And just to finish this up, is i positive or negative?
