Lesson: Linear Transformations in Planes: Scaling Mathematics

Start Practising

In this lesson, we will learn how to find the matrix that scales a vector by a given scaling factor and the image of the vector under scaling linear transformation.

Lesson Plan

Students will be able to

  • calculate the image of a single vector under a scaling linear transformation,
  • calculate the image of a shape in the 2D plane under a scaling linear transformation,
  • interpret the geometric effect of applying a given scaling matrix,
  • find the matrix that represents a scaling of a vector or shape by a given factor.
