(d^2y)/(dx^2)-6(dy)/(dx)+9y=xe^x

Lösung

\frac{d ^{2} y}{d x ^{2}} - 6 \frac{d y}{d x} + 9 y = x e^{x}

y = c_{1} e^{3 x} + c_{2} x e^{3 x} + \frac{e ^{x} x}{4} + \frac{1}{4} e^{x}

Schritte zur Lösung

\frac{d ^{2} y}{d x ^{2}} - 6 \frac{d y}{d x} + 9 y = x e^{x}

Solve linear ODE:

y = c_{1} e^{3 x} + c_{2} x e^{3 x} + \frac{e ^{x} x}{4} + \frac{1}{4} e^{x}

y = c_{1} e^{3 x} + c_{2} x e^{3 x} + \frac{e ^{x} x}{4} + \frac{1}{4} e^{x}

t an g e n t f (x) = 2 x^{3} - 8 x, (- 2, 0)

\int ((4 x + 3) \cdot (2 x^{2} + 3 x)^{3}) d x

f (x) = x \cdot sin (x)

\frac{d}{d x} (\frac{8 x ^{2} + 2 x + 8}{x})

x \to + 0 lim (x sin (\frac{3}{x}))
