Find the angle formed when [4,4,2] and [4,3,12] are placed tail to tail ; then find the components of the vector that results when [4,3,12] is projected onto [4,4,2].
My answer is 48.189 for the angle.
101 = 169 + 36 - 2X13X6Xcos a
cos a = 0.666666667
Is it correct?
For the second part, I am not sure what it means to project a vector onto another one.
