integral of (cot(3+ln(x)))/x

\int \frac{cot ( 3 + ln ( x ) )}{x} d x

ln ∣ sin (3 + ln (x)) ∣ + C

Solution steps

\int \frac{cot ( 3 + ln ( x ) )}{x} d x

Apply u-substitution

= \int cot (u) d u

Rewrite using trig identities

= \int \frac{cos ( u )}{sin ( u )} d u

Apply u-substitution

= \int \frac{1}{v} d v

Use the common integral:

\int \frac{1}{v} d v = ln (∣ v ∣)

= ln ∣ v ∣

Substitute back

= ln ∣ sin (3 + ln (x)) ∣

Add a constant to the solution

= ln ∣ sin (3 + ln (x)) ∣ + C
