$$\int\limits_{-1}^{0} 1 \cdot \frac{1}{e^{x}} \frac{1}{x^{2}}\, dx$$

Integral(1/(E^x*x^2), (x, -1, 0))

Detail solution

UpperGammaRule(a=-1, e=-2, context=1/(E**x*x**2), symbol=x)

Add the constant of integration:

$- \frac{\operatorname{E}_{2}\left(x\right)}{x}+ \mathrm{constant}$

The answer is:

$- \frac{\operatorname{E}_{2}\left(x\right)}{x}+ \mathrm{constant}$
