1 ------ - tan(x)*y = 0 cos(x)
$$- y \tan{\left(x \right)} + \frac{1}{\cos{\left(x \right)}} = 0$$
Resolución de la ecuación paramétrica
Se da la ecuación con parámetro:
$$- y \tan{\left(x \right)} + \frac{1}{\cos{\left(x \right)}} = 0$$
Коэффициент при y равен
$$- \tan{\left(x \right)}$$
entonces son posibles los casos para x :
$$x < 0$$
$$x = 0$$
Consideremos todos los casos con detalles:
Con
$$x < 0$$
la ecuación será
$$y \tan{\left(1 \right)} + \frac{1}{\cos{\left(1 \right)}} = 0$$
su solución
$$y = - \frac{1}{\sin{\left(1 \right)}}$$
Con
$$x = 0$$
la ecuación será
$$1 = 0$$
