(x(dy)/(dx)+2y)=3

解答

(x \frac{d y}{d x} + 2 y) = 3

y = - \frac{c _{1}}{2 x ^{2}} + \frac{3}{2}

求解步骤

(x \frac{d y}{d x} + 2 y) = 3

求解可分离方程:

y = - \frac{c _{1}}{2 x ^{2}} + \frac{3}{2}

y = - \frac{c _{1}}{2 x ^{2}} + \frac{3}{2}

t an g e n t f (x) = 9 - x, at x = 2

y^{^{'}} = e^{8 x + y}

\frac{\partial}{\partial y} (z e^{x y})

x \to 1 lim (3 x^{3} - 4 x^{2} + x + 2)

\frac{\partial}{\partial x} (ln (x^{3} + y) - z)
