When i develop integrals, changing the coordinates (cartesian-> polar for example), i always forget how to write infinitesimal surface or volume.(adsbygoogle = window.adsbygoogle || []).push({});

Is there a sort of rule to derivate it?

I mean, an intuitive way to remember it, not the mathematical derivation.

(another thing: i've the same problem with the Prosthaphaeresis formulas)
