    try \int_0^a \sqrt{1+t^2}~dt

    or
    \int_0^a \sqrt{(1+t)^2}~dt

    depending on which you were shooting for.

    Consider \sqrt{ } to be a function, so anything inside must be within those brackets. The tilde creates a space. the caret will raise the object to it's left to the power of the first digit to it's right, so a^bc = a^bc if you want a^(bc) you need to write it as a^{bc} = a^{bc}

    Generally if you are unsure, place {} around your terms, when you get more comfortable with it, you can start using shortcuts like \frac 12 = \frac{1}{2}. So you could write 5/(3x+2) as \frac{5}{3x+2} or as \frac 5{3x+2} and you could write (3x+2)/5 as \frac{3x+2}{5} or \frac {3x+2}5

    Hello, free_to_fly!

    You want the radical to contain 1+t^2 ?

    A square root is written: .\sqrt{ . }
    . . . . . . . . . . . . . . . . . . . . . . . {\color{blue}\uparrow}
    Now insert the radicand between the braces: .\sqrt{1 + t^2}

    . . . . \int_0^a \sqrt {1 + t^2}\,dt

    s=\sqrt{a^2 + b^2 + c^2}


    f(t)=A\cos(\omega t+\alpha)

    \frac{d}{dt} f(t)= -A\omega\sin(\omega t+\alpha)

    \int^a _{b} f(t) dt =

    Name confusion

    Well, I've managed to come up with a puzzle.

    Why doesn't [tex]\text{Name}[/tex] give "Name" as an output?
