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.

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