integral of ln(tan(x))sec^2(x)

\int ln (tan (x)) sec^{2} (x) d x

ln (tan (x)) tan (x) - tan (x) + C

Solution steps

\int ln (tan (x)) sec^{2} (x) d x

Apply Integration By Parts

= ln (tan (x)) tan (x) - \int sec^{2} (x) d x

\int sec^{2} (x) d x = tan (x)

= ln (tan (x)) tan (x) - tan (x)

Add a constant to the solution

= ln (tan (x)) tan (x) - tan (x) + C

What is the integral of ln(tan(x))sec^2(x) ?
The integral of ln(tan(x))sec^2(x) is ln(tan(x))tan(x)-tan(x)+C
