derivative of (dy/(dx))+81y=0

\frac{d}{d x} (\frac{d y}{d x}) + 81 y = 0

y = c_{1} cos (9 x) + c_{2} sin (9 x)

Solution steps

\frac{d ^{2} y}{d x ^{2}} + 81 y = 0

Solve linear ODE:

y = c_{1} cos (9 x) + c_{2} sin (9 x)

y = c_{1} cos (9 x) + c_{2} sin (9 x)

\int cos (\frac{u}{v}) d u

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

\int 6 t^{4} e^{- t^{5}} d t

4 e^{(\frac{2 t}{3})}

\int \frac{1}{x ^{3} x ^{2} - 25} d x
