Hi, I'm having a hard time understanding how Cylindrical Coordinates work in Mathematica. I have several questions: 1. What is the expression for unit vectors in Cylindrical Coordinates in Mathematica? For example is this correct: r_unit = {1,0,0}, phi_unit = {0,1,0}, and z_unit = {0,0,1}??? 2. How do you perform vector cross product of these unit vectors in Cylindrical coordinates in Mathematica? for example: CrossProduct [ {1, 0, 0}, {0, 1, 0}] gives = {0, 0, 0} which is not the correct answer, then how am I supposed to be doing it? Can anyone please help? thanks in advance!
