The Angle Between Vectors - Concept

Concept Concept (1)

The vector formula to find the angle between vectors is a useful formula to memorize. This formula uses the dot product, magnitude and cosine to give us the angle between vectors. We can use this formula to not only find the angle between vectors, but to also find the angle between planes and the angle between vectors in space, or in the 3D coordinate system.
