$$y = c_{1} \cos{\left(\frac{x}{4} \right)} - c_{2} \sin{\left(\frac{x}{4} \right)}$$
Solución detallada
Tenemos la ecuación:
$$y = c_{1} \cos{\left(\frac{x}{4} \right)} - c_{2} \sin{\left(\frac{x}{4} \right)}$$
cambiamos:
$$y = c_{1} \cos{\left(\frac{x}{4} \right)} - c_{2} \sin{\left(\frac{x}{4} \right)}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
y = c1*cosx/4 - c2*sinx/4

Obtenemos la respuesta: y = c1*cos(x/4) - c2*sin(x/4)
