# Reference request: Vector calculus for PDE

I am looking for a good textbook/online notes that treat vector analysis theoretically, but more from a analysis/pde approach (emphasis on divergence theorem and symbolically computing integrals), and less from a differentiable manifolds approach (heavy emphasis on generalized Stoke's theorem).

Ideally it would give a good sense about how to compute in hyperspherical coordinates (example: spherical averages from Evan's pde chapter 2) but I will definitely settle for not going full $\mathbb{R}^n$ with $n>3$. I ask because I am having some difficulties with some of the vector calculus in PDE and haven't been able to find anything suitable online or in the library.

Hopefully this isn't asking too much. Thank you very much!
