Ecuación diferencial y''''=4cos^3*x-x
El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
5
x cos(3*x) 2 3
y(x) = C1 + 3*cos(x) - --- + -------- + C2*x + C3*x + C4*x
120 81
$$y{\left(x \right)} = C_{1} + C_{2} x + C_{3} x^{2} + C_{4} x^{3} - \frac{x^{5}}{120} + 3 \cos{\left(x \right)} + \frac{\cos{\left(3 x \right)}}{81}$$
