y^{''}+8y^'+18y=0,y(0)=1,y^'(0)=2

y^{^{''}} + 8 y^{^{'}} + 18 y = 0, y (0) = 1, y^{^{'}} (0) = 2

y = e^{- 4 t} (cos (2 t) + 32 sin (2 t))

Solution steps

y^{''} (t) + 8 y^{'} (t) + 18 y = 0

Solve linear ODE:

y = e^{- 4 t} (cos (2 t) + 32 sin (2 t))

y = e^{- 4 t} (cos (2 t) + 32 sin (2 t))

\int_{- \infty}^{- 1} \frac{1}{x} d x

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

\frac{d}{d x} (\frac{x + 1}{x ^{2} + x - 2})
