y^'+3(tan(3x))y=7cos(3x)

解

y^{^{'}} + 3 (tan (3 x)) y = 7 cos (3 x)

解

y = \frac{7 x}{sec ( 3 x )} + \frac{c _{1}}{sec ( 3 x )}

解答ステップ

y^{'} (x) + 3 (tan (3 x)) y = 7 cos (3 x)

線形 ODE を解く:

y = \frac{7 x}{sec ( 3 x )} + \frac{c _{1}}{sec ( 3 x )}

y = \frac{7 x}{sec ( 3 x )} + \frac{c _{1}}{sec ( 3 x )}
