please provide the limits to help us solve the query.
Are you sure that you typed the correct problem? The correct question would be
[0 ][ /2]log (tan x + cot x)
2) put cosx as 1-t^2/1+t^2 & sinx as 2t/1+t^2 .
where t-> tan(x/2)
P.N : I TRIED this 1 on 3pgs B4 Being fed up. fromm next time do provide ans. & yEs LIMITS.
FROM WHERE DID U GeT THi$ Qn.
I'm damn sure the problem is right. puneet1622 I haven't posted it wrong. A friend of mine (cleared JEE 2006) gave me this prob with a warning that everyone will tell me it is non-integrable but it is. Sadly, he didn't give me the answer can you help me get to the answer?
(2/3) [ tan-1 (cos x + sinx ) + 2 tanh-1 ( ( tan (x/2) +1 ) / 2 ) ]
and natural logarithmic variables whose properties I don't remember at this moment.
because ln z = ln |z| +i arg (z) where is z is a complex number.
(1/2) i ( ( x2+ polylog (2 , e 2ix ) ) where i = -1
