Gráfico de la función
Puntos de cruce con el eje de coordenadas X
El gráfico de la función cruce el eje X con f = 0
o sea hay que resolver la ecuación:
$$\sin^{2}{\left(\frac{3 x}{5} \right)} \cos{\left(\frac{3 x^{2}}{10} \right)} - \frac{1}{5} = 0$$

Extremos de la función
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
$$- \frac{3 x \sin^{2}{\left(\frac{3 x}{5} \right)} \sin{\left(\frac{3 x^{2}}{10} \right)}}{5} + \frac{6 \sin{\left(\frac{3 x}{5} \right)} \cos{\left(\frac{3 x}{5} \right)} \cos{\left(\frac{3 x^{2}}{10} \right)}}{5} = 0$$
