Rotation of spherical vectors

  1. Oct 31, 2008 #1
    I have a vector v(r, theta, phi) in one coordinate space.

    I need to calculate the values r', theta' and phi' for the same vector in another coordinate space which is rotated by alpha, beta and gamma about the x, y and z axis respectively
    Is there an easy way to do this?

    Thanks

    Robert

    Welcome to PF!

    Hi Robert! Welcome to PF! :smile:

    (have an alpha: α and a beta: β and a gamma: γ and a theta: θ and a phi: φ :wink:)
    Not that I know of … except that r =r' :redface:

    (you could try http://en.wikipedia.org/wiki/Euler_angles)

    Euler angles is probably the standard way to do this (I know it's how I was taught) but they're a bit of a pain to do. I recommend switching to a subject that doesn't rotate vectors
