Best ResponseYou've already chosen the best response.0I spose if the "rectangular" system is (x,y,z) axis that we could convert it to spherical....

Best ResponseYou've already chosen the best response.0x = r cos(t) y = r sin(t) z = ..... r cos(w) ?? dunno what to make for the z :)

Best ResponseYou've already chosen the best response.0Theta is the same. x=rho*sin phi*cos theta, y=rho*sin phi *sin theta, z=rho*cos phi, r=rho*sin phi

Best ResponseYou've already chosen the best response.0Also, rho^2=x^2+y^2+z^2. Phi is the angle that rho makes with the positive z axis, 0<=rho<=pi. So, it usually isn't much trouble going from rectangular to polar or cylindrical and then to sperical.

Best ResponseYou've already chosen the best response.0Amistre; just remarking: My book (and several others, I feel like somebody would have a better name by now) refers to 3dimensional, xyz coordinate systems, as "rectangular coordinate" systems. Despite both spherical and cylindrical being named after exclusively 3dimensional objects.

Best ResponseYou've already chosen the best response.0"Rectangular cuboid, right cuboid, rectangular box, rectangular hexahedron, right rectangular prism, or rectangular parallelepiped" don't ring very well. Something like "prismatic coordinates" or "prism coordinates" sounds cool but makes an unsaid assumption that you are dealing with right rectangular prisms.
