integral of e/x+x/e

Solution

\int \frac{e}{x} + \frac{x}{e} d x

Solution

e ln ∣ x ∣ + \frac{x ^{2}}{2 e} + C

Solution steps

\int \frac{e}{x} + \frac{x}{e} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int \frac{e}{x} d x + \int \frac{x}{e} d x

\int \frac{e}{x} d x = e ln ∣ x ∣

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

= e ln ∣ x ∣ + \frac{x ^{2}}{2 e}

Add a constant to the solution

= e ln ∣ x ∣ + \frac{x ^{2}}{2 e} + C
