(2x)/y dx-(x^2)/(y^2)dy=0

解答

\frac{2 x}{y} d x - \frac{x ^{2}}{y ^{2}} d y = 0

y = c_{1} x^{2}

求解步骤

\frac{2 x}{y} d x - \frac{x ^{2}}{y ^{2}} d y = 0

求解可分离方程:

y = c_{1} x^{2}

y = c_{1} x^{2}

d er i v a t i v e f (x) = \frac{2 x}{7} + 1

\int (\frac{3}{x ^{\frac{3}{4}}} - 4 3 x + 1) d x

\frac{d y}{d x} = (x - 2) e^{- 2 y}

\frac{\partial}{\partial x} ((2 - x) (5 - x - 2 y))

x \to 2 lim (\frac{3 x + 4}{5 x + 7})
