hiiii

just put tan(-1)x as t .. n thn use the integration by parts

u shall get the answer ..

i hope this helps

cheers

we are not getting d ans like dis..............

thanks for the response puneet bhaiyya..but m still stuck

multiply ((1+x^2)^2)/((1+x^2)^2)

then take ( tan(-1)x(1+x^2)) as the integrable func.

then apply by parts i think this shall solve the prob

sandeepramesh

try it. I dont think it will work after wolfram has said that there is a complex soln or no soln exists :)

sandeepramesh

plzzz dont rate for this and all, its embarrasing
