    Antiderivative Help!

    I havent done antiderivatives in a while, Im wondering if the antiderivative of

    2/(x^2 + 1)
    is just
    (ln|x^2 + 1|)/x
    Thanks for the help

    Note quite

    \int \frac{2}{x^2+1}dx=2\tan^{-1}(x)

    If you need the detail let me know.

    Remember you can always check by taking the derivative and see if you get the original back.
