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$$\frac{- \frac{e^{\sin{\left(\frac{1}{x} \right)}} \sin{\left(\frac{1}{x} \right)}}{x^{2}} + \frac{e^{\sin{\left(\frac{1}{x} \right)}} \cos^{2}{\left(\frac{1}{x} \right)}}{x^{2}}}{x^{2}} + \frac{2 e^{\sin{\left(\frac{1}{x} \right)}} \cos{\left(\frac{1}{x} \right)}}{x^{3}} = 0$$
