61) true u= v=<-12,6>  0 x -12 + 0 x 6  0+0  0 orthogonal  63) u= v= cosB x sinB+sinB x -cosB cosBsinB-sinBcosB 0 orthogonal 64) u dot v=0 they are orthoganal u dot v>0 the angle is more than 90  u dot v<0 the angle is greater than 90

Peter's deal got erased so i copied and pasted it from the history. I got the same stuff. Checked by Quinn Taylor
