Question

Again plz, definite integrals?

Answer 1

\[\int\limits_{2}^{3}\left( 1/\left( xlnx \right) \right)dx\]

Answer 2

let lnx = u, du = 1/x dx

Answer 3

Did you try u=ln(x) ? :)

Answer 4

i cant get it

Answer 5

\[\int\limits_{}^{}\frac{1}{\ln(x)} \cdot \frac{1}{x} dx\]

Answer 6

\[\int\limits_{}^{}\frac{1}{u} du\]

Answer 7

so its ln(lnx) +K this is the next step right?

Answer 8

\[ \ln \left| \ln\left| 3 \right| \right|- \ln \left| \ln\left| 2 \right| \right|\]

Answer 9

thank you all so much
