y^{''}+7y^'-18y=0

y^{^{''}} + 7 y^{^{'}} - 18 y = 0

y = c_{1} e^{2 t} + c_{2} e^{- 9 t}

Solution steps

y^{''} (t) + 7 y^{'} (t) - 18 y = 0

Solve linear ODE:

y = c_{1} e^{2 t} + c_{2} e^{- 9 t}

y = c_{1} e^{2 t} + c_{2} e^{- 9 t}

\frac{x - 5 x x}{x}

x \to 5 lim (\frac{12}{5 - x})

\int \frac{1}{100 - x ^{2}} d x

x \to 3 lim (2 (x + 3))

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