    You can learn how to make the LaTeX symbols (clicking on an image will show you the text you need to use)


    Also, many text symbols can be made:

    & radic ; = √
    & rarr ; = →
    & alpha ; = α
    & Psi ; = Ψ
    & infin ; = ∞


    Not to mention anything you can look up in the Character Map in windows (provided you're looking at the right font)

    For example, a degree symbol (°) can be made by typing ALT-0176. (You must use the numeric pad, and hold alt throughout the entire sequence)

    [tex] S = \sum_{n=0}^\infty \frac{i^n}{n!} \idotsint \ {d^4x_1}\ {d^4x_2}
    \dots \ d^4x_n \ T (H_I(x_1) \ H_I(x_2) \dots \ H_I(x_n) )
    [/tex]
