x=tan-1p
dx=1/1+p2dp
∫ptan-1pdp/1+p2
now i think u r smart enough to integrate by parts[1]
aggar koi prob hai to ask
1AIR 1 .. humlog chote aadmi hai .. tum toh AIR 1 ho . .khud hi integrate kar lo ...
11@ankit, i have written it as air1 because i think aiming higher(along with hard work) will fetch us a gud rank
11FIR TU YAHAN PAR JHAKH MAAR RAHA HAI
IT IS
TARGET IIT
NOT TARGET INTEGRATE NON INTEGRABLE FUNCTIONS
MERE DIMAG MEIN NAYA IDEA AAYA SO I SHARED IT [1]
1mani ko bolo na woh apna eq . solve kare ... AIR 1 i was jus joking ..
21in the integral part OF " by - PARTS "
U'll get ∫(tan-1p)2/2
this ^^^ cud prov nightmares...... i.e. if u take p as the differentiable function in MANI's Equation
