Definition of scalar product and angles between vectors
Check what you remember
Read the wording for your board, then hide it and explain scalar product and angles between vectors in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: WJEC
The sum of the products of corresponding components, and a · b = |a||b|cos θ gives the angle between vectors.
