Multiply Complex Numbers in Polar Form
- Suzanne Doering
Question to answer: What modulus and argument results when we multiply two complex numbers? Move the two complex numbers to explore patterns in their products.
1) Summarize the rule for finding the product of two complex numbers in polar form. 2) Find the product 2cis(pi/6)*3cis(4pi/3) using your rule. Then verify your result with the app. 3) Find an exact value for cos (5pi/12).
