Para hallar los extremos hay que resolver la ecuación
$$\frac{d}{d x} f{\left(x \right)} = 0$$
(la derivada es igual a cero),
y las raíces de esta ecuación serán los extremos de esta función:
$$\frac{d}{d x} f{\left(x \right)} = $$
primera derivada$$- \frac{\sin{\left(\frac{1}{2 - x} \right)}}{\left(2 - x\right)^{2} \left(2 - x\right)^{2}} + \frac{\left(4 - 2 x\right) \cos{\left(\frac{1}{2 - x} \right)}}{\left(2 - x\right)^{4}} = 0$$
