comment Troubles with integrals and WA
I think that in your next to last expression (right after "and I got") all the terms following the RHS integral sign are actually in the integral.

comment computing a triangular region using 'line integral' of stoke's theorem
Would advise that you edit accordingly. Will be clearer for people who might want to answer.

comment computing a triangular region using 'line integral' of stoke's theorem
The three vertices should each have three components. Is it assumed that they are all in one plane?

comment Why integration constant is real?
In principle you're right. In practice, it's just good pedagogy to take things one step at a time.

comment evaluate a Fraunhofer diffraction integral
I mean that in the summation expression, you have a $k_G$ on the LHS, but not on the RHS. Should the $k$ on the RHS be $k_G$?

comment evaluate a Fraunhofer diffraction integral
Was going to provide a possible solution, but I realize I'm confused about a few things. 1) n in your summation does not appear in your expression. This can't be right. 2) Should x in the summation be x-prime? 3) Where does $k_G$ go? I am tempted to say that once you make the substitution, the integrand becomes a sum of straightforward exponentials, but I'm not sure.

comment How to tell what rotation operation a matrix performs?
The Wikipedia link is a good entry. I would just be repeating what they say.
