(dy)/(dx)=(e^{x-y})/(1+e^x)

Lösung

\frac{d y}{d x} = \frac{e ^{x - y}}{1 + e ^{x}}

y = ln (ln (1 + e^{x}) + c_{1})

Schritte zur Lösung

\frac{d y}{d x} = \frac{e ^{x - y}}{1 + e ^{x}}

Solve separable ODE:

y = ln (ln (1 + e^{x}) + c_{1})

y = ln (ln (1 + e^{x}) + c_{1})

\int \frac{x ^{2}}{( x ^{2} - 1 ) ^{\frac{3}{2}}} d x

t an g e n t f (x) = x^{2} - 5 x, at x = - 2

\int 9 x sin (x) cos (x) d x

t an g e n t f (x) = ∣ x ∣ 5 - x^{2}, (2, 2)
