Solución

Ha introducido [src]
cos(y) = sin(y)
$$\cos{\left(y \right)} = \sin{\left(y \right)}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(y \right)} = \sin{\left(y \right)}$$
cambiamos:
$$- \frac{\sin{\left(y \right)}}{\cos{\left(y \right)}} = -1$$
o
$$- \tan{\left(y \right)} = -1$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -1

La ecuación se convierte en
$$\tan{\left(y \right)} = -1$$
Esta ecuación se reorganiza en
$$y = \pi n + \operatorname{atan}{\left(-1 \right)}$$
O
$$y = \pi n - \frac{\pi}{4}$$
, donde n es cualquier número entero
