    I have seen the application of this formula in one of the journal papers . I just want to know is there any such relation ( or even other such type ) between exponential and complimentary error function ?

    So you think:

    [tex]e^{a^{2}} \frac{2}{\sqrt{\pi}} \int_{a}^\infty e^{-t^{2}} dt = e^{a^{2} \frac{2}{\sqrt{\pi}} \int_{a}^\infty e^{-t^{2}} dt }[/tex] ?

    Looks like nonsense to me. I would be very leery about this if there were no proof in this journal you're talking about.

    Even I have tried this counter example but is there any substantiating answer through calculus ?
