  1. Multiplication, Division & DeMoivre’s Theorem ES: Making decisions after reflection and review Warm-Up: Convert -8 – 8i into trigonometric form.

  2. Multiplying in Trig (cis) Form

  3. Dividing in Trig (cis) Form

  4. Examples: Evaluate with the help of trig form if needed. Show your answer in both trig & standard form. • (3 – 3i)(-2 – 2i)

  5. Examples: Evaluate. 2) (3cis90°)(5cis45°)

  6. Examples: Evaluate with the help of trig form if needed. Show your answer in both trig & standard form. 3)

  7. Examples: Evaluate 4)

  8. DeMoivre’s Theorem

  9. Examples: Evaluate 5) 4(1 - i√3)3

  10. Evaluate. Leave your answer in trig form with the argument in the interval

  11. Closure: Evaluate, putting your final answer in standard form. Check your answer on your calculator
