Answer #1

Cos-1 1/4 = 75.5225o = 75.5225 x /180 = 1.3186 radians, where = 22/7

Cos-1 1 = 0o = 0 x /180 = 0 radians

we cannot have cos values greater than 1. therefore Cos (theta) = 3/2 = 1.5 is not possible. If you meant cos theta = Sqrt(3)/2, then Cos-1 = 60o = 60 x /180 = 1.0476 radians

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...
