When doing Angular Momentum, how is it that 2.0(2.12i + 2.12j) x (-3.863i - 1.035j) is equal to 2.0[-2.194k + 8.189k]?
I don't understand.'cos i x j = k and j x i = -k (and ii = jj = 0)
he he :rofl:I don't understand.
cos i x j = k ?
So cos 2.12i x 2.12j = -2.194k ?
O! I get it! Thanks.he he :rofl:
no, I meant because i x j = k
