comment Prove $\sin(x)< x$ when $x>0$ using LMVT
Or you can juste choose $x$ in $(0,+\infty)$ from the beginning.

comment Show that $|z+1|\le|z+1|^2 +|z|$ for all $z \in \mathbb{C}$
I think it's badly written : "If $1\leqslant |z+1|$, then $|z+1|\leqslant|z+1|^2$ hence $|z+1|\leqslant |z+1|^2+|z|$, now I must show that the inequality is also true when $|z+1|<1$, but this is where I'm stuck."
