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