y^{''}+36y=-2tan(6x)

Lösung

y^{^{''}} + 36 y = - 2 tan (6 x)

y = c_{1} cos (6 x) + c_{2} sin (6 x) + \frac{cos ( 6 x ) ln ( tan ( 6 x ) + sec ( 6 x ) )}{18}

Schritte zur Lösung

y^{''} (x) + 36 y = - 2 tan (6 x)

Solve linear ODE:

y = c_{1} cos (6 x) + c_{2} sin (6 x) + \frac{cos ( 6 x ) ln ( tan ( 6 x ) + sec ( 6 x ) )}{18}

y = c_{1} cos (6 x) + c_{2} sin (6 x) + \frac{cos ( 6 x ) ln ( tan ( 6 x ) + sec ( 6 x ) )}{18}

\frac{d}{d x} ((\frac{sin ( x )}{cos ( 2 x )})^{3})

f^{^{'}} (x) = 3 cos (x) + 4 (- sin (x))
