I'm asked to show if there exists $z$ in $\mathbb{C}$ such that, the two following conditions are simultaneously satisfied
$|\sin(z)|>1, |\cos(z)|>1$
For $|\sin(z)|^2$ I find $\displaystyle\frac{1-\cos(2z)}{2}$ wich is not a real number in general because $\cos(z)$ is not a real number. I don't know where is the mistake.
