What is your favorite integral?

    I do love the Gaussian Integral. It's a beautiful one for sure.

    Also though,

    ∫(sin x)/x (over all space)

    is a great one.

    And just to top it of

    [tex] \int \sin(\ln x) + \cos(\ln x) dx[/tex]
    [tex] \int_{\mathbb{R}} \sin(x^2) + \cos(x^2) dx[/tex]
    [tex] \int (2x^2+1)e^{x^2} dx[/tex]
    [tex] \int \frac{x^2}{x^2+4x+8} dx[/tex]
    [tex] \int \frac{x e^x}{(1+x)^2} dx[/tex]
    [tex] \int \frac{x^{29}}{\left( 5x^2 + 49 \right)^{17}} dx[/tex]

    But yeah, the list of my favourite integrals changes from day to day so :p
