I've been told that for upper level physics classes it's imperative to know how to switch between coordinate systems, however I'm unsure of what is exactly necessary to know. For example, today I was reading up on divergence and I noticed that there are formulas for(adsbygoogle = window.adsbygoogle || []).push({});

divergence in spherical and cylindrical coordinates. Same with the laplacian etc. What does one actually need to know by the time they are taking mechanics with differential equations or a little later quantum mechanics? Should these just be memorized? It's not that I'm opposed to learning how to derive them, but I'm a little more ahead in my physics than my math. Thanks
