y^{''}+4*y=cos(x)

Lösung

y^{^{''}} + 4 \cdot y = cos (x)

y = c_{1} cos (2 x) + c_{2} sin (2 x) + \frac{1}{3} cos (x)

Schritte zur Lösung

y^{''} (x) + 4 \cdot y = cos (x)

Solve linear ODE:

y = c_{1} cos (2 x) + c_{2} sin (2 x) + \frac{1}{3} cos (x)

y = c_{1} cos (2 x) + c_{2} sin (2 x) + \frac{1}{3} cos (x)

\frac{d}{d x} (\frac{x}{x ^{2} + 225})

\int_{1}^{4} x^{2} - 5 x + 4 d x

t an g e n t x^{\frac{3}{2}} + x^{\frac{1}{2}}

x \to 1 lim (\frac{3 - x}{3 + x} e^{- x} cos (π x))
