    yes same, have seen it 2-3 times before

    and, i know this is called the gaussian integral, is there any way we(students preparing for JEE)can solve it

    I don't post problems that cannot be solved by your JEE prep. knowledge. If you solved it using any method that you haven't learned in class, consider your solution wrong.

    It can be done and here's a hint:

    Try to introduce some variables (other than x, I mean) into the 1st integration.

    Bhaiya, is there any way to prove that the 1st integral is sqrt(pi)? i tried wiki and read quite a lot about error function, but everywhere they have just defined the same like a result

    There is infact a very simple way, based on double integration. That's beyond your scope.

    But, there is a quite straightforward way to derive the second integral from the 1st.
