sin(2*z)
f(z) = --------
z + 1
$$f{\left(z \right)} = \frac{\sin{\left(2 z \right)}}{z + 1}$$
f = sin(2*z)/(z + 1)

Extremos de la función
Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d z} f{\left(z \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d z} f{\left(z \right)} = $$
primera derivada
$$\frac{2 \cos{\left(2 z \right)}}{z + 1} - \frac{\sin{\left(2 z \right)}}{\left(z + 1\right)^{2}} = 0$$

Puntos de flexiones
Hallemos los puntos de flexiones, para eso hay que resolver la ecuación
$$\frac{d^{2}}{d z^{2}} f{\left(z \right)} = 0$$
(la segunda derivada es igual a cero),
