Determine the value of integral from -pie to pie [2x(1+sin(x)]/[1+cos(x)*cos(x)]
sorry i can't provide it's answer because i am not able to tex tags i tried a lot but every time i am getting error. that doesn't print things as it should. see this(next line) where am i wrong
[tex]\frac{2x(1+sinx)}{1+cos^2x}[\tex]. did you see it's effect.?
My steps of solving question are.
(1) change x by -x(property)
(2)put cos(x)=t upper and lower limmit will became equal so it's answer should zero but it's answer is not zero.
It's answer is pie square. i have reached to pie square. How. After first step the integration can also be written as limit 0 to pie(do also twice of it). After that i solve it ans reached to answer pie square.
Afterall my question is why it' answer came zero if i put cos(x)=t in first case.
where can i found the pdf or htm file containing the way of using tex or any other such things.
