You have three unknowns Ux, Vy and Wz. You are told that they areOriginally Posted byjaycas21

mutually perpendicular, and you are to use the dot product.

The dot product of perpendicular vectors is zero, so you have:

U.V=0,

U.W=0,

V.W=0.

Form these dot products and you will have three linear simultaneous

equations which you then need to solve.

Dot product of two vectors: and is:

,

where , and are the unit vectors along a set of perpendicular axes.
