Outcomes

In this lesson you will learn

  • the relationship between rectangular coordinates, (x, y), and polar coordinates, (r,)
  • to convert complex numbers in rectangular form to polar form
  • to convert from polar form to rectangular form
  • the meaning of r cis

By the end of this section students will be able to:

  • represent complex numbers in a variety of ways
  • apply operations on complex numbers both in rectangular and polar form
  • construct and examine graphs in the complex and polar planes
  • translate between polar and rectangular representation
