integral of 9+1/x

Solution

\int 9 + \frac{1}{x} d x

Solution

9 x + ln ∣ x ∣ + C

Solution steps

\int 9 + \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 9 d x + \int \frac{1}{x} d x

\int 9 d x = 9 x

\int \frac{1}{x} d x = ln ∣ x ∣

= 9 x + ln ∣ x ∣

Add a constant to the solution

= 9 x + ln ∣ x ∣ + C
