Question

How do I solve this integral (I'll post it on a reply)

Answer 1

\[\int\limits_{}^{}\sin (x)\times \tan (x) dx\]

Answer 2

use integration by parts

Answer 3

it's just int (sin^2/cos) and yes integration by parts

Answer 4

use the general formula which is int u dv= uv int v du

Answer 5

u= sin(x)
dv=tan(x) dx

Answer 6

agree with enorcrux and quakine that u need to use integration by part

Answer 7

thnx now I see how the 3 answers are ok :) but the idea of enocrux is better than use integration by part with the tan(x)

Answer 8

\[\int\limits_{?}^{?} u dv= uv- \int\limits_{?}^{?} v du\]

Answer 9

sorry forget the minus sign but anyhow u know the idea
