well this is a general question on integrating root of trignometric functions

u all must hav done integration of root of tanx and root of cotx

if anyone of u how to integrate root of sinx, cosx, cosecx or secx then pls post it here !!

This requires Elliptic Integrals of Second Kind..It is Out of course!!

kbanagar

well let me try..

put Sinx=t²
.dxcosx=2tdt
dx=dt/cosx
I =??sinx=?t x 2t x dt?cosx
=2?t²dt?cosx
=2?t²dt??1-sin²x
=2?t²??1-t²
and I?m stuck here??.
Pls do chk if I?m a bit correct n sum1 else continue so that I?ll come to know..

kbanagar

by the way what are elliptic integrals..{do nudge me}

kbanagar

hullo.........
anyone there pls reply

put sinx=(e^ix-e^-ix)/2i

then it wil b easy 2 solve

rate if correct
