calculate A dot(c cross b) for A:(-3,2,3), B:(4,-2,2) and C:(5,3,4). what is the angle betw A & C cross B?

Answer 1

calculate cross product

|i j k|
|5 3 4|
|4 -2 2|
thats a determinant then do the dot product

-3(i part from above) + 2(j part from above) + 3(k part from above

to find the angle between two vectors lets say M and N
cos x = (M x N) / ( ||M|| ||N|| ) ||M|| = magnitude of M
i'll leave it up to you
