    Hi, I'm having difficulty integrating the following exponential, is there a rule I need to learn for these type of exponentials?

    ʃe^x^2.5 dx



    Thanks.

    Can't be done in terms of elementary functions: http://integrals.wolfram.com/index.j...5&random=false

    I presume you mean e^{(x^{2.5})} rather than (e^x)^{2.5}; the latter can be easily integrated.

    Have you been given any specific limits? In which case GA's first interpretation does lead to solutions with specific limits.

    What module is this for?
    How do you do the latter one anyway?

    (a^b)^c = a^{bc}

    That's helpful.

    Could you express what you are trying to say in a different way? I don't know what you are referring to either.

    It has been explained here, and on the other thread where you asked

    You are not expected to integrate e^{x^n}

    Carry on like this and we will all conclude you are trolling.

    The thread is perfectly clear about which one can and can't be integrated in terms of elementary functions.
