y^{''}+4y=-3x^2+2x+3

Lösung

y^{^{''}} + 4 y = - 3 x^{2} + 2 x + 3

y = c_{1} cos (2 x) + c_{2} sin (2 x) - \frac{3 x ^{2}}{4} + \frac{x}{2} + \frac{9}{8}

Schritte zur Lösung

y^{''} (x) + 4 y = - 3 x^{2} + 2 x + 3

Solve linear ODE:

y = c_{1} cos (2 x) + c_{2} sin (2 x) - \frac{3 x ^{2}}{4} + \frac{x}{2} + \frac{9}{8}

y = c_{1} cos (2 x) + c_{2} sin (2 x) - \frac{3 x ^{2}}{4} + \frac{x}{2} + \frac{9}{8}
