Solución detallada
Tenemos la ecuación
$$e \cos{\left(x \right)} \left(1 - \cos{\left(y \right)}\right) = c$$
es la ecuación trigonométrica más simple
Dividamos ambos miembros de la ecuación en -E*cos(x)
La ecuación se convierte en
$$\cos{\left(y \right)} = - \frac{c - e \cos{\left(x \right)}}{e \cos{\left(x \right)}}$$
Esta ecuación se reorganiza en
$$y = \pi n + \operatorname{acos}{\left(- \frac{c - e \cos{\left(x \right)}}{e \cos{\left(x \right)}} \right)}$$
$$y = \pi n + \operatorname{acos}{\left(- \frac{c - e \cos{\left(x \right)}}{e \cos{\left(x \right)}} \right)} - \pi$$
O
$$y = \pi n + \operatorname{acos}{\left(- \frac{c - e \cos{\left(x \right)}}{e \cos{\left(x \right)}} \right)}$$
$$y = \pi n + \operatorname{acos}{\left(- \frac{c - e \cos{\left(x \right)}}{e \cos{\left(x \right)}} \right)} - \pi$$
