Question

what is the integral of {sin(x)tan(x)}

i tried turning tan(x) into sin(x)/cos(x) then doing u substitutions but i always have an extra sin(x) left.

can you help me pleeeease

Answer 1

sin(x) tan(x) = sin²(x)/cos(x) = (1-cos²(x))/cos(x) = sec(x) - cos(x)

Now you can probably handle it, yes?

Answer 2

wooow, i cant believe ive been staring at it this long and couldn't see this. thanks!!
