Dominio de definición de la función
Puntos en los que la función no está definida exactamente:
$$x_{1} = 0$$
$$x_{2} = 1.5707963267949$$
$$x_{3} = 4.71238898038469$$
$$x_{1} = 0$$
$$x_{2} = 1.5707963267949$$
$$x_{3} = 4.71238898038469$$
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:
$$\frac{\sin^{2}{\left(x \right)}}{x^{2} \cos^{2}{\left(x \right)}} = 0$$
