find

(i) (AxB)xC & Ax(BxC)

**drwls**, Monday, November 2, 2009 at 4:58amI'll start this out, using the determinant rule for vector cross products. You do the last part, and check my work for errors.

A x B =

|i j k|

|1 1 0|

|2 -3 1| = i -j -5k

(AxB) x C =

|i j k|

|1 -1 -5|

|0 4 -3| = 17i + 3j +4k
