integral of e^x*x^{-2}

integral

e^{x} \cdot x^{- 2}

- \frac{e ^{x}}{x} + Ei (x) + C

Solution steps

\int e^{x} x^{- 2} d x

Simplify

e^{x} x^{- 2} : \frac{e ^{x}}{x ^{2}}

= \int \frac{e ^{x}}{x ^{2}} d x

Apply Integration By Parts

= - \frac{e ^{x}}{x} - \int - \frac{e ^{x}}{x} d x

\int - \frac{e ^{x}}{x} d x = - Ei (x)

= - \frac{e ^{x}}{x} - (- Ei (x))

Simplify

= - \frac{e ^{x}}{x} + Ei (x)

Add a constant to the solution

= - \frac{e ^{x}}{x} + Ei (x) + C
