#Calc 3 spherical coords fins phi how to#
Please your advice on how to solve this and the thought process behind. Cylindrical Coordinates - from Wolfram MathWorld 12.7: Cylindrical and Spherical Coordinates. import numpy as np import quaternion as q theta np.pi 1.0 / 3.0 phi 0.0 print (q.fromsphericalcoords (theta,phi)) This quaternion is a 60 degrees rotation around Y axis, but I expected a 60 degrees rotation around Z axis only, since phi is 0.0. For this geometric definition, S represents a sphere that is centered at ( x, y, z) that is oriented outward. Then I would take inverse sign which would give me the max angle for $φ$ and therefore would know the bound, in this case I don't know and I don't know how to find it, I was considering using cylindrical coordinates instead but it led to a tedious integral. While trying to understand the usage the quaternion extension of numpy, I saw that. Where $c$ and $a$ are positive constants. I have a sphere and a cone making up a region.
