1. The problem statement, all variables and given/known data I'm suppose to verify the given Laplace in (a) Cartesian (b) Sperical and (c) Cylindrical coordinates. (a) was easy enough but I need to know if I'm doing (b) and (c) correctly. I don't need a solution, I simply need to know if the my Spherical formula is correct, my Cylindrical formula is correct and lastly, if my value of p is the same for both (b) and (c). is p=rsinθ valid for both Cylindrical and Spherical points? 2. Relevant equations 3. The attempt at a solution See the upload.
