yes. the goal is to show this $z_0$ is actually a root of $p$.

comment How do I figure out if a 'function is odd or even'?
sure. For example, suppose $f(x) = x^2$. Since $f(-x) = (-x)^2 = (-x)(-x)= x^2 = f(x)$, we conclude that $f(x) = x^2$ is even.

I think I got it. Do I have to use the formulas $$ \sin x - \sin y = 2 \sin ( \frac{x+y}{2} ) \cos ( \frac{ x -y }{2} ) $$ ?

what you mean by a whole number? Also, the same is true for the sine function ?
