integral of (sec(x)tan(x))/(sec(x)-2)

\int \frac{sec ( x ) tan ( x )}{sec ( x ) - 2} d x

ln ∣ sec (x) - 2 ∣ + C

Solution steps

\int \frac{sec ( x ) tan ( x )}{sec ( x ) - 2} d x

Apply u-substitution

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= ln ∣ u ∣

Substitute back

u = sec (x) - 2

= ln ∣ sec (x) - 2 ∣

Add a constant to the solution

= ln ∣ sec (x) - 2 ∣ + C
