    How to integrate this integral?

    Hi all,

    I want to calculate the integral \int^t_0 \frac{\sin(t')}{\sqrt{t-t'}}dt', where t is just a constant. It should be converged since \int^t_0 \frac{1}{\sqrt{t-t'}}dt' is computable. Thanks.

    Hey Mengqi.

    After looking at Wolfram Alpha, there is absolutely no way I would have guessed the solution to your problem but anyway - the link is below:

    int sin(u)*(a-u)^(-1/2)du - Wolfram|Alpha

    Chiro,

    Thank you very much! I've never heard of Fresnel function.. I thought the integration would be trivial since its simple looking....
    I will look into that.
