Ecuación diferencial -12*y'+4*y''+y'''=8*e^(2*x)*(sin(2x))/2
El profesor se sorprenderá mucho al ver tu solución correcta😉
Solución
-6*x / 5*sin(2*x) 3*cos(2*x)\ 2*x
y(x) = C1 + C3*e + |C2 - ---------- - ----------|*e
\ 68 68 /
$$y{\left(x \right)} = C_{1} + C_{3} e^{- 6 x} + \left(C_{2} - \frac{5 \sin{\left(2 x \right)}}{68} - \frac{3 \cos{\left(2 x \right)}}{68}\right) e^{2 x}$$
