Question

integrate this

Answer 1

\[\int\limits_{}^{} (1 / x)\cos(\ln(x))dx\]

Answer 2

what happens if you let u=lnx then du=dx/x correct?

Answer 3

so we have int(cosu, u) = sin u+c = sin(lnx)+c where c is a constant

Answer 4

it gives me integral: cos(ln(x))du

Answer 5

but you have to integrate the natural log too

Answer 6

right?

Answer 7

\[\int\limits_{}^{}cosu du\]
