I am not sure if this is the right site to ask this question, but here it is:

Does Wolfram Alpha do contour integrals? If so how might I access that feature. Also, is there an online manual for Wolfram?

Many thanks.

    If you parameterize the contour then it should be possible. Did you have a specific integral in mind?2012-05-17

    @AntonioVargas: Not really but say I want to integrate z along the unit circle, what should I type in?2012-05-17

    @AntonioVargas: Ah I see how it works now, thanks! Nonetheless, is there some sort of manual available for WA?2012-05-17

    @user17762 I am not supposed to ask a question like this here maybe, but I don't know another place to get the answer. I want Wolfram to calculate an inegral of $\frac{alnx}{b+x}$ but I don't know what to type in the box where I ask the question2018-12-16

Here are two ways the integral $$\int_C \frac{d z}{z},$$ where $C$ is the unit circle traversed counterclockwise, can be handled:

(1) using the definition of a complex line integral;

(2) using the residue theorem.

I have found all I need to know about Wolfram Alpha here. Here are some pages relevant to contour integration.
