Homework Help: calculus

Posted by angles on Wednesday, August 24, 2011 at 10:45am.

Find two unit vectors that make an angle of 60 with v = 3, 4. Give your answers correct to three decimal places.

I'm not sure what to do here; I believe that I use to definition of a dot product (or maybe cross product) with relation to the trig function (cos for dot, sin for cross) but for whatever reason I can't get my answer to come out.
