# Dot Product

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

Drag either of the two vectors to move them. The angle between the vectors is shown (in blue when acute and in red when obtuse). The unit circle is shown for scale. The vectors can be constrained to be unit vectors, in which case the dot product is the cosine of the angle between them.
