D(x)=-6(2940)+4200

解

D (x) = - 6 (2940) + 4200

x = c_{1} - 13440 t

解答ステップ

D x = - 6 \cdot 2940 + 4200

線形 ODE を解く:

x = c_{1} - 13440 t

x = c_{1} - 13440 t

y^{^{''''}} - 16 y = 2 e^{- 2 x} + 3 e^{3 x} + cos (2 x) - 1

\frac{d ^{2}}{d t ^{2}} (θ (t)) + 4 θ (t) = cos (c^{2}) (2 t)

\frac{d ^{2} x}{d t ^{2}} + 100 x = 36 cos (8 t)

y^{^{''}} - 6 y^{^{'}} + 9 y = t^{- 7} e^{3 t}

x^{^{''}} + 2 x^{^{'}} - 4 x = 6 e^{3 t} - 4 t + 3
