Indefinite Integration

$\frac{\mathrm{e}^x}{(x+1)}+\mathrm{c}$, (where c is constant of integration)

$\frac{\mathrm{e}^{\mathrm{x}}}{(x+1)^2}+\mathrm{c}$, (where c is constant of integration)

$\frac{-\mathrm{e}^x}{(x+1)}+\mathrm{c}$, (where c is constant of integration)

$\frac{-\mathrm{e}^x}{(x+1)^2}+\mathrm{c}$, (where c is constant of integration)
