Philip Calvert ·2009-02-08 07:01:44

ok what i meant was

by using by parts straight away we get

x(tan-1x)² - âˆ« (2xtan^-1x/1+x²)dx

tan^-1x = t

==> âˆ«2t.tant dt

note that second term by both methods is same [11]
i wonder whether limits will be same as well
wow mathemagic !![4]

Philip Calvert ·2009-02-08 06:29:12

take (tan^(-1)x)^2 as first funcion and 1 as 2nd and use by parts method

for the second term use again by parts
dont' forget to simplify the second term i think it will be âˆ«tan^-1 t dt

sorry it will be a dirty method but should give answer

Philip Calvert ·2009-02-08 06:39:28

by putting tan^-1x=t and assuming i am not sleeping(which i am)
it will be
âˆ«t²/sec²t dt

what then [7][7]

*edited sorry it will be âˆ«t²sec²t dt
anyways what next [7]
