I know of two ways to compute the angle between two vectors 1.) cos theta = (u· v)/(||u||· ||v||) 2.) sin theta = ||u x v||/(||u||· ||v||) The problem I need help with requires that I show that the two methods produce the same theta value. The vectors I have to work with are u = <-2,2,-2> and v = <4,6,3>. Theoretically, the two theta values should be the same. However, when I did it both ways, the first method...
