The magnitude of the scalar product of vectors A and B is three times as large as the magnitude of the vector product of the same two vectors. If they were placed tailtotail in space, A and B would form an angle of approximately how much?

The magnitude of AxB is C=ABsinθ
while the magnitude of A.B is
D=ABcosθ
So if
D/C=3 => cotθ=3
Solve for θ
