theta is an angle, and so is psi.
with respect to what? Which one is the reference line?
Hello everyone,
I have a quick and straightforward problem, that I need some help with.
Suppose I have a spherical vector defined by a radius and two angles, denoted by <rho,theta,psi>. Where, rho is the radius, theta is an angle, and so is psi.
Which that being said, how would I convert that spherical vector into a Cartesian vector.
(Note: I know how to convert from Spherical to Cartesian;
x=rho*sin(psi) *cos(theta)
Y=rho*sin(psi) *sin(theta)
Z=rho*cos(theta)
Would these conversion also be appropriate if the input is a spherical vector, and the required output is a Cartesian vector.
Thanks for the help.

Theta= The angle of rotation around Y on the XZ plane
Psi= The angle of rotation around Z on the YX plane
So the reference direction would be X? Is that right, if I knew the formula I am sure I could swap variables out into their proper location for my coordinate system
Your equations to convert from spherical to cartesian are incorrect. The x and y must have sin(theta) in them, where theta is the polar angle (measured down from the positive z axis), and z must have cos(theta) in it. What changes in x and y is the trig function of the azimuthal angle (measured around the z axis).
