The answer has helped understand the theory more, but I still feel confused as to how the author came up with $F(x_1,x_2)$ and $G(x,t)$ in the first line of each proof, their use seems a little magical to me still. Dec24 comment Motivation for constructing $F$ s.t. $\ker(\text{curl}) \subset \text{Im}(\text{grad})$, $\ker(\text{div}) \subset \text{Im}(\text{curl})$ @Travis I don't. Dec24 comment Motivation for constructing $F$ s.t. $\ker(\text{curl}) \subset \text{Im}(\text{grad})$, $\ker(\text{div}) \subset \text{Im}(\text{curl})$ I apologise for the dreadful LaTeX. I am using a keyboard I am not used to using.

I am. Apologies. I meant a contour that does not stop at any finite point (that is, goes off to infinity in both directions). Nov29 asked How is half-contour integration possible? Nov19 comment Is there a general way to prove series and products are modular? @user45195 The mild moral qualm about reposting this question is stronger than my attachment to reputation.
