Homework Help: Angles from the positive x-axis

  1. Feb 13, 2008 #1
    1. The problem statement, all variables and given/known data
    In the problem sin-1 is 59.1. I have to give it from the positive x axis.

    2. Relevant equations

    3. The attempt at a solution

    Would it be 360-59.1? or 180-59.1?

    Thank you very much

    Try to give some more information. "sin-1 is 59.1" doesn't make sense.

    Sorry. I have inverse sine as 59.1, but I need to give it in the form of the positive x-axis? Would I need to take 180-59.1?

    Thank you

    So you need to find a direction of a vector in your probelme and you have computed that that vector has an angle of 59.1 with something. What is that something, and in wich side of that something is the 59.1 angle.

    If 59.1 would be in a clockwise direction away from the negative x-axis your answer would be right.
