    Integral of e^x/2?

    Integral of e^x/2?

    I've looked in my book for a forumla to work something like this out but can't find it. All it said was the integral of e^x/2 = 2e^x/2, so I'm guessing the formula is e^x/a = ae^x/a?

    Hope you can help, thanks.

    Yes. \int e^{x/a} \, dx = a e^{x/a} + C.

    It follows from the standard form \int e^{kx} \, dx = \frac{1}{k} e^{kx} + C, where k = \frac{1}{a}.
