Ans:Hello student, please find answer to your question
I = \int e^{x}.tanx(1-2sec^{2}x)dx
I = \int e^{x}(tanx-2sec^{2}x.tanx)dx
f(x) = tanx
f'(x) = sec^{2}x
f''(x) = 2sec^{2}x.tanx
I = \int e^{x}(f(x)-f''(x))dx
I = \int e^{x}(f(x)+f'(x)-f'(x)-f''(x))dx
I = e^{x}(f(x)-f'(x)) + constant
I = e^{x}(tanx-sec^{2}x) + constant
