y^{''}+121y=sec(11x),y(0)=-5,y^'(0)=6

Lösung

y^{^{''}} + 121 y = sec (11 x), y (0) = - 5, y^{^{'}} (0) = 6

y = - 5 cos (11 x) + \frac{6}{11} sin (11 x) + \frac{1}{121} ln (cos (11 x)) cos (11 x) + \frac{x sin ( 11 x )}{11}

Schritte zur Lösung

y^{''} (x) + 121 y = sec (11 x)

Solve linear ODE:

y = - 5 cos (11 x) + \frac{6}{11} sin (11 x) + \frac{1}{121} ln (cos (11 x)) cos (11 x) + \frac{x sin ( 11 x )}{11}

y = - 5 cos (11 x) + \frac{6}{11} sin (11 x) + \frac{1}{121} ln (cos (11 x)) cos (11 x) + \frac{x sin ( 11 x )}{11}

\frac{\partial}{\partial y} (3 x (y - 1)^{\frac{1}{3}})

\frac{d}{d x} (- \frac{9 x}{y})

\frac{\partial}{\partial y} (x^{2} + y e^{x})

\frac{\partial}{\partial y} (ln (x - 6 y))
