(dy}{dx}-\frac{2y)/x =x^2sin(3x)

Lösung

\frac{d y}{d x} - \frac{2 y}{x} = x^{2} sin (3 x)

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

Schritte zur Lösung

\frac{d y}{d x} - \frac{2 y}{x} = x^{2} sin (3 x)

Solve linear ODE:

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

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