(dy)/(dx)+7(tan(7x))y=2cos(7x)

Lösung

\frac{d y}{d x} + 7 (tan (7 x)) y = 2 cos (7 x)

y = \frac{2 x}{sec ( 7 x )} + \frac{c _{1}}{sec ( 7 x )}

Schritte zur Lösung

\frac{d y}{d x} + 7 (tan (7 x)) y = 2 cos (7 x)

Solve linear ODE:

y = \frac{2 x}{sec ( 7 x )} + \frac{c _{1}}{sec ( 7 x )}

y = \frac{2 x}{sec ( 7 x )} + \frac{c _{1}}{sec ( 7 x )}
