Operator: Vector Dot Product is a Number Spell Piece added by Psi. It provides the dot product of two vectors, which is defined as , where and are vectors, and are the magnitudes of the two vectors, and is the angle between the two vectors. For example, two vectors at a 90° angle will have a dot product of 0, while those at a 0° angle will be exactly equal to . This result is scalar; it will result in a number value, not another vector. This should not be confused with
Operator: Vector Multiply and
Operator: Vector Cross Product. It is unlocked in the lesson "Trigonometry."

## Parameters

• Vector A: Requires a vector.
• Vector B: Requires a vector.
