Simple Trig question

  1. Dec 12, 2006 #1
    1. The problem statement, all variables and given/known data
    [​IMG]
    Given Distance and Theta, how do I find (x,y)?

    This is for a programming project and I don't remember my Trig very well.


    2. Relevant equations
    That is what I am after.


    3. The attempt at a solution
    dist/x = cos theta, dist/y = sin theta, solve for x,y?

    Its really just the soh cah toa rules if you want to think of it like that. The distance is the hypotenuse and x is the adjacent and y is the opposite.

    So x = dist * cos theta, y = dist * sin theta?
