possible bug on spherical coordinates graphs
Mahoma Iza Villalba shared this question 3 years ago
Hi, I was experimenting with the spherical coordinates graphing feature for surfaces, and I found that to graph things properly we need to write pi/2 - phi instead of just phi to produce the standard graphs.
I suppose that phi is being measured with respect to the xy plane instead of with respect to the positive Z axis.
Not sure if this was intended that way. Graphing rho constant (the sphere) is not affected by this, but the cone and the semi-polar plane for theta and phi constants are not the correct ones unless you use pi/2 - phi, as shown in the link
