SOLUTION: Evaluate and express your answer in trigonometric form:
3(cos π/3 + i sin π/3)*4(cos π/12 + i sin π/12)
I'm sorry if that is hard to read. I couldn't get the formula plot

Question 1173366: Evaluate and express your answer in trigonometric form:
3(cos π/3 + i sin π/3)*4(cos π/12 + i sin π/12)
I'm sorry if that is hard to read. I couldn't get the formula plotting system to work. Answer by ikleyn(52932) (Show Source):
Use the basic formula for multiplying complex numbers in trigonometric form
if =
and
= ,
then
= .
It gives, in your case, for the product the ANSWER = .
If you want EVALUATE it further, calculate and , using your calculator.
