y^{''}+9y^'+14y=0

Lösung

y^{^{''}} + 9 y^{^{'}} + 14 y = 0

y = c_{1} e^{- 2 t} + c_{2} e^{- 7 t}

Schritte zur Lösung

y^{''} (t) + 9 y^{'} (t) + 14 y = 0

Solve linear ODE:

y = c_{1} e^{- 2 t} + c_{2} e^{- 7 t}

y = c_{1} e^{- 2 t} + c_{2} e^{- 7 t}

t an g e n t f (x) = ln (\frac{x + 2}{x ^{2}}), at x = 1

\frac{d}{d x} (\frac{( ln ( x ) ) ^{3}}{x ^{3}})

x \to 0 lim (x^{2} - 3 x + 1)

n = 1 \sum \infty \frac{1}{( 4 n ) ^{2} - 1}

x \to - 1 + lim (- 1)
