(e^y+1)^2e^{-y}dx+(e^x+1)^3dy=0

解答

(e^{y} + 1)^{2} e^{- y} d x + (e^{x} + 1)^{3} d y = 0

求解步骤

(e^{y} + 1)^{2} e^{- y} d x + (e^{x} + 1)^{3} d y = 0

求解可分离方程:

\int 4 e^{x} + 12 x^{3} + 4 x d x

t an g e n t f (x) = 2 sin (x), at x = \frac{π}{4}

d er i v a t i v e e^{x^{2} - x}

s l o p e y = 3 + 4 x^{2} - 2 x^{3} x = a
