I prompted Wolfram Alpha with this integration problem: "integral of (4x^3)/(x^4-8)"
It returns a strange complex result, where it assumes the complex logarithm.
Why does it do this instead of returning the more obvious real result of log(|x^4-8|)? All it is missing is the absolute value.
Am I missing something? I just wanted to report this incase it was an unexpected result. Thanks
