Writing unit vectors in terms of sin/cos?

  1. Oct 20, 2010 #1
    Where could I find a webpage or guide on how to write unit vectors in terms of sin and cos? I looked through my textbook and tried searching google, but I can't find anything...I must be using the wrong terminology.


    edit: Delete me! I had one of those epiphany moments and figured it out. :blushing:

    For the record, in case anyone requires it in the future.

    Use Soh Cah Toa (trigonometry):
