\int \tan (3 x-5) \sec (3 x-5) d x=

View answer and explanation

Correct option: B

\frac{1}{3} \sec (3 x-5)+c

Option B is correct because substituting

t = 3x - 5

transforms the integral to

\frac{1}{3} \int \tan t \sec t dt

, which equals

\frac{1}{3} \sec t + c = \frac{1}{3} \sec(3x - 5) + c
