cos (x - 1) = 0
$$\cos^{2}{\left(x - 1 \right)} = 0$$
Solución detallada
Tenemos la ecuación
$$\cos^{2}{\left(x - 1 \right)} = 0$$
cambiamos
$$\cos^{2}{\left(x - 1 \right)} = 0$$
$$\cos^{2}{\left(x - 1 \right)} = 0$$
Sustituimos
$$w = \cos{\left(x - 1 \right)}$$
Tenemos la ecuación
$$\cos^{2}{\left(x - 1 \right)} = 0$$
es decir
$$\cos{\left(x - 1 \right)} = 0$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
cos-1+x = 0

Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\cos{\left(x - 1 \right)} + 1 = 1$$
Esta ecuación no tiene soluciones
hacemos cambio inverso
$$\cos{\left(x - 1 \right)} = w$$
Tenemos la ecuación
$$\cos{\left(x - 1 \right)} = w$$
es la ecuación trigonométrica más simple
Esta ecuación se reorganiza en
$$x - 1 = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x - 1 = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
O
$$x - 1 = \pi n + \operatorname{acos}{\left(w \right)}$$
$$x - 1 = \pi n + \operatorname{acos}{\left(w \right)} - \pi$$
, donde n es cualquier número entero
Transportemos
$$-1$$
al miembro derecho de la ecuación
con el signo opuesto, en total:
$$x = \pi n + \operatorname{acos}{\left(w \right)} + 1$$
$$x = \pi n + \operatorname{acos}{\left(w \right)} - \pi + 1$$
sustituimos w:
