its calculus

is it t+1 in the bracket

no its inside log

Is that
\[ \int_1^x \frac{B\cdot \log(1+t)}{1+t^2} dt \]

\[\int\limits_{0}^{1} \frac{8\ln(1+t)}{1+t^2} \]

its this ^

This looks like a pretty nasty integral, what class is this for? :)

My first thought would be integration by parts, actually.

ok now i got it

help

\[\pi \log(2)\]

~~2.17759

integral of 1/(1+t^2) is tanx

arctan^

yehh jemurray typo

dhash i have simplified enuf lol

i got '0=0' thats why i am asking you

use integration by parts, i have told u what to integrate and what to differentiate ,

i didnot get the ans in that way

yep jem is right

Now, just plug in the limits.

With respect Aron, we all know how to use wolfram alpha.

haha jem

jem bt what else cud b easier way other than by parts to teach a high scool student

i know jemm im tryin to simplify it

Try x = tan y

yeah got it place t =arctany
then its simple

cool thanks that works
