    Complex Number Questions

    Hi, I have been unable to do these questions (any help would be great):
    1. Simplify sin(x)+sin(2x)+...+sin(nx)

    2. Let z^13=w and w^11=z. Prove that Im(z)=sin{(m*pi)/n} if both z and w are complex numbers, where m and n are positive integers with no common factors.

    Thanks
