How can I find 2 vectors from the dot products of themselves.

Let p and q be vectors in R3. Suppose p * p = 36, q * q = 25 and the angle between them is pi / 6.

Find p * q

How can I find 2 vectors from the dot products of themselves.

Find p * q

Use the fact that: If A and B are two coplanar vectors

A ^. B = ||A|| * ||B|| * cos(Θ) ................. where Θ is the angle between the two vectors. Continue....
