Question

If a =k b, what is the angle between a and b where k is a scalar quantity?​

Answer 1

We can use this form of the dot product to find the measure of the angle between two nonzero vectors. The following equation rearranges Equation 2.3 to solve for the cosine of the angle: cosθ=u·v‖u‖‖v‖. Using this equation, we can find the cosine of the angle between two nonzero vectors.
