Help with coordinate problem

  1. Aug 8, 2005 #1
    I have been thinking about this problem for awhile, but have no idea to even begin solving it. Was wondering if anyone has a clue to help me started?
    There's a point (x0,y0,z0) in 3D. There is a line on the X-Y plane. This line is say theta degrees (0 - 360) about the Y-axxis. If the point (x0, y0, z0) is rotated phi degrees about this line, what is the new position?
    This is just a problem I thought up, so I don't even know if there is enough information to solve it.
    Please help me, let me know what's a good step to solve it? Should I use Cartesian system, or use another one?
    Thanks!

    There are 'infinity' of lines that form the same angle with the y-axis. So if the exact line's not given, I don't think this is solvable.
    Anyway, are you sure this statement is correct???
    Shouldn't that be 0 <= theta <= 90????
    Viet Dao,
