Homework Help: Complex number(exponential form)

  1. Dec 18, 2009 #1
    Let z = 4e^i(pi/6)
    find iz and |e^iz|

    what is iz?
    is it imaginary part of z?

    No, "iz" is exactly what it looks like: i times z. The difficulty appears to be that z is in polar form while i is in "rectangluar" form. Either write i in polar form or write z in rectangular form. Then multiply.

    That was what I meant when I said "Either write i in polar form or write z in rectangular form. Then multiply." What is i in polar form? What is z in rectangular form?
