Let u = tanx
du=sec^2x dx
Can u go from there and try and solve it now?

I tried doing it by trig identities but i’ll have a go at that

so don’t see that working because you would get cosx/sec^2x

sec^2(x) tan(x)

#

integrates to sec(x)

#

if im not wrong

#

sec^2(x)

#

mb

#

then for the tan(x)cos(x)

#

it simplifies to sin(x)

I integrated to get sec^2x then decided to do it again for some reason
