integral of (e 1/x)/(x^2)

\int \frac{e \frac{1}{x}}{x ^{2}} d x

- \frac{e}{2 x ^{2}} + C

Solution steps

\int \frac{e \frac{1}{x}}{x ^{2}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= e \cdot \int \frac{\frac{1}{x}}{x ^{2}} d x

Simplify

\frac{\frac{1}{x}}{x ^{2}} : \frac{1}{x ^{3}}

= e \cdot \int \frac{1}{x ^{3}} d x

Apply the Power Rule

= e (- \frac{1}{2 x ^{2}})

Simplify

e (- \frac{1}{2 x ^{2}}) : - \frac{e}{2 x ^{2}}

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

Add a constant to the solution

= - \frac{e}{2 x ^{2}} + C
