Solución

Ha introducido [src]
cos(x) = 1/5
$$\cos{\left(x \right)} = \frac{1}{5}$$
Solución detallada
Tenemos la ecuación
$$\cos{\left(x \right)} = \frac{1}{5}$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x = \pi n + \operatorname{acos}{\left(\frac{1}{5} \right)}$$
$$x = \pi n - \pi + \operatorname{acos}{\left(\frac{1}{5} \right)}$$
O
$$x = \pi n + \operatorname{acos}{\left(\frac{1}{5} \right)}$$
$$x = \pi n - \pi + \operatorname{acos}{\left(\frac{1}{5} \right)}$$
, donde n es cualquier número entero

Respuesta rápida [src]
x1 = -acos(1/5) + 2*pi
$$x_{1} = - \operatorname{acos}{\left(\frac{1}{5} \right)} + 2 \pi$$
x2 = acos(1/5)
$$x_{2} = \operatorname{acos}{\left(\frac{1}{5} \right)}$$
x2 = acos(1/5)
