sorry here

OpenStudy (jhannybean):

\[\int \log(x)\log(x+2)dx\]

OpenStudy (jhannybean):

@Kainui

rvc (rvc):

im so tensed yes @Jhannybean correct

Parth (parthkohli):

Not expressible in elementary functions.

Parth (parthkohli):

@rvc are you a high-school student?

Parth (parthkohli):

unless we're talking about definite integrals or something, i don't really know what to do here.

Parth (parthkohli):

WA confirms!

OpenStudy (kainui):

You could turn one of those logs into a power series which amounts to finding the general formula for \[\Large \int\limits x^n \log(x) dx\]

rvc (rvc):

@ParthKohli u in high school?

Parth (parthkohli):

no, im in kindergarten.....!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!111

Parth (parthkohli):

OK, so I just checked with WA and it looks like they performed IBP a several number of times before arriving to a well-known function that can be expressed in terms of Li.

rvc (rvc):

@Kainui i know the integral for the above question u mentioned

rvc (rvc):

well we can substitute logx = t

OpenStudy (jhannybean):

Goodnight, I'll check out Parth's explanation tomorrow.

Parth (parthkohli):

i can't see how that improves the situation :(

Parth (parthkohli):

@rational pls

rvc (rvc):

hey logx =t e^t=x right

Parth (parthkohli):

that's correct, dt = 1/e^t dx

rvc (rvc):

nope |dw:1427273643883:dw|
