Ans:
Hello Student,
Please find answer to your question below

$I = \int \frac{tanx}{secx+tanx}dx$
$I = \int \frac{tanx(secx-tanx)}{(secx+tanx)(secx-tanx)}dx$
$I = \int \frac{secxtanx-tan^2x}{sec^2x-tan^2x}dx$
$I = \int \frac{secxtanx-tan^2x}{1}dx$
$I = \int secxtanxdx-\int tan^2xdx$
$I = \int secxtanxdx-\int (sec^2x-1)dx$
$I = \int secxtanxdx-\int sec^2xdx+\int dx$
$I =secx-tanx+x+c$
