integral from 1 to 3 of e^x*ln(x)

\int_{1}^{3} e^{x} \cdot ln (x) d x

e^{3} ln (3) - Ei (3) + Ei (1)

Solution steps

\int_{1}^{3} e^{x} ln (x) d x

Apply Integration By Parts

= [e^{x} ln (x) - \int \frac{e ^{x}}{x} d x]_{1}^{3}

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

= [e^{x} ln (x) - Ei (x)]_{1}^{3}

Compute the boundaries:

e^{3} ln (3) - Ei (3) + Ei (1)

= e^{3} ln (3) - Ei (3) + Ei (1)
