VIC: Dot Product
by Texas Instruments

Objectives

This activity provides a dynamic and visual representation of the dot product where students can manipulate the two vectors to explore the conditions under which the dot product is positive, zero and negative in addition to understanding the formation of the dot product.

Vocabulary

  • Vector
  • Scalar
  • Magnitude
  • Dot Product

About the Lesson

Students are provided with a number of functions that help illustrate the geometric transformations associated with the absolute value function. Particular focus is drawn to notation such as f(|x|) and |f(x)|. Students can see the original function and the resulting absolute value function making it easier to draw comparisons.
