(d^2y)/(dx^2)+14(dy)/(dx)+98y=0

\frac{d ^{2} y}{d x ^{2}} + 14 \frac{d y}{d x} + 98 y = 0

y = e^{- 7 x} (c_{1} cos (7 x) + c_{2} sin (7 x))

Solution steps

\frac{d ^{2} y}{d x ^{2}} + 14 \frac{d y}{d x} + 98 y = 0

Solve linear ODE:

y = e^{- 7 x} (c_{1} cos (7 x) + c_{2} sin (7 x))

y = e^{- 7 x} (c_{1} cos (7 x) + c_{2} sin (7 x))

(3 x y^{2} + 1 y) d x + (3 x^{2} y + 1 x) d y = 0

\int cos (3 x) sin^{4} (3 x) d x

\frac{d y}{d x} = (4 x - 1) (y + 5)

\int (x + 2) (x - 2) d x

\int \frac{x}{1} (1) d x
