About the Lesson
The lesson starts by exploring how the magnitude of vector a affects the scalar resolute of a on b. Students then explore how the change in angle affects the scalar resolute including an angle of 90 degrees and 0 degrees. Students use geometric representations to determine a formula for the scalar resolute and complete conceptual, numerical and algebraic questions relating to the scalar resolute. A companion video file to help students understand the concepts is also provided in the lesson materials via a link.
