    Parenthesis

    Parenthesis again.

    [rant]

    \int 8x + 5 sin(x)~dx is not a valid expression. \int (8x + 5 sin(x))~dx is!!!!

    [/rant]

    Thank you for your time.

    Re: Parenthesis

    Great example, thanks! However:

    [Gotcha_mode=ON]
    "Parenthesis" is singular, as in one mark "(" or ")." "Parentheses" is plural. Typically math expressions use parentheses in pairs, though a bracket and a single parenthesis may be used to denote a half-closed interval as in [3,8).
    [Gotcha_mode=OFF]

    Re: Parenthesis

    That is, however, probably one of the least egregious "lack of parentheses" errors. We have both " \int" and "dx" to mark off the integrand. It is not nearly as bad as, say, "x^2- 3x+ 1/x^2+ 3x+ 4".
