Complex exponential signal?

Ive been out of school for about 15 years. I am taking a discrete course online and have this homework problem. I don't know where to start. I am working with my old diff eq books to get caught up but need help.

Given the complex exponential signal: y(t)=3*exp(j*pi/3)*exp(j*10*pi)

a) What is the imaginary part i(t)?

b)What are the frequency and period of i(t)?

c)What is the real part r(t)?

d)What is the value of r(t) at t=10ms?

e) At what time incidents does r(t) reach maximum or minimum?
