integral of 7+1/x

Solution

\int 7 + \frac{1}{x} d x

Solution

7 x + ln ∣ x ∣ + C

Solution steps

\int 7 + \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 7 d x + \int \frac{1}{x} d x

\int 7 d x = 7 x

\int \frac{1}{x} d x = ln ∣ x ∣

= 7 x + ln ∣ x ∣

Add a constant to the solution

= 7 x + ln ∣ x ∣ + C
