Ecuación diferencial y’’’’+8*y’’+16*y=cos(2*x)
El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
/ / x \\
y(x) = (C1 + C2*x)*sin(2*x) + |C3 + x*|C4 - --||*cos(2*x)
\ \ 32//
$$y{\left(x \right)} = \left(C_{1} + C_{2} x\right) \sin{\left(2 x \right)} + \left(C_{3} + x \left(C_{4} - \frac{x}{32}\right)\right) \cos{\left(2 x \right)}$$
