See the sin(x) dx? Well you have du = - sin(x) dx and u = cos(x)
I think I can do it now.
Because you are already done! Look at the numerator and what du equals.
Are you familiar with integration by substitution?
But why are you doing this?
du = - sin(x) dx
I am lost.
That is the first step. Set u = cos(x)
Write tan(x) = sin(x)/cos(x).
I use a package or a table.
Ha ha ha! So, thats called the chain rule!
I mean about the chain rule. You did it!
Math is Fun. I am not sure if it is funny
That was funny, right?
