Investigation 2: Multiplying and Dividing Complex Numbers

Step F

The graph of 2w is a dilatation of w by a factor of 2.

The graph of -5w is a dilatation of w by a factor of -5.

Step H

You will need to recall the multiplication of binomials, and the fact that:

 (a + b)(c + d) can be calculated as a(c + d) + b(c + d).
