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
