Hi, I am trying to integrate a quantity
1/(Cos[theta] - Sin[theta]*Cos[phi])
over a spherical surface within the limits (theta, 0, ArcCot[Cos[phi]]) and (phi, 0, Pi/4). Due to some issue, which I am not able to figure out, not getting it done. Would be thankful if someone can help. Attached is the *.nb file with the code. Thanks in advance - SG
