Question

what is the integral of 1/(xln(x))dx please show work

Answer 1

Hint: let u = lnx

Answer 2

ohhhhhhhh thank you i feel really dumb now

Answer 3

hehe..it takes practice to see these kinds of things ^_^ just practice :)

Answer 4

ya ill get it eventually I hope but hey so since u=lnx then du = 1/x so would it substitute to be 1/u du cause that doesn't seem right

Answer 5

yup that's about right...

du = 1/x dx so \(\int \frac{1}{x \ln x} dx = \int \frac{1}{u} du\)

Answer 6

ok ya nevermind i'm sorry its kinda late where I am that is like calc one stuff but thank you for helping my confusion
