(dy)/(dx)=0.04-y/7

解答

\frac{d y}{d x} = 0.04 - \frac{y}{7}

y = - e^{\frac{- x - c _{1}}{7}} + 0.28

求解步骤

\frac{d y}{d x} = 0.04 - \frac{y}{7}

求解可分离方程:

y = - e^{\frac{- x - c _{1}}{7}} + 0.28

y = - e^{\frac{- x - c _{1}}{7}} + 0.28

\frac{d y}{d x} + 6 x^{2} y = 7 x^{2}, y (0) = 2

\frac{d y}{d x} = \frac{e ^{8 y + x}}{x}, x > 0

\frac{d}{d t} ((x) x) = t^{2} + 1

y^{^{'}} = 8 x sec (y)

(5 x + 4) + (5 y - 5) y^{^{'}} = 0
