Dear Nikhil,

Try with by parts integration
1st is x^(1/2)
2nd is sinx
Now
I = x^(1/2) * (-cosx) - $\int$(1/2) (1/x^(1/2)) (- cos x) dx
Now again integrate the later part by by parts
You get there is again an algebric fn with sin x
Now take this again as I.
Now you have to give the value of I.

Dear Nikhil,
I suppose it should not work.
Because (root x)*(sinx) does have an antiderivative. The solution does not exist.
