integral of e^x-1/x

Solution

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

Solution

e^{x} - ln ∣ x ∣ + C

Solution steps

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

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

\int \frac{1}{x} d x = ln ∣ x ∣

= e^{x} - ln ∣ x ∣

Add a constant to the solution

= e^{x} - ln ∣ x ∣ + C
