Afternote: Originally when I published this post I made an error in the “vector calculus” summary. I wrote divergence as du/dx, du/dy, du/dz —- this should actually by du/dx, dv/dy, dw/dz — the error has been fixed but if you downloaded these notes any earlier than 3rd May 2017 there is a chance that you downloaded the version with the error! Sorry guys !
