3. ### How do you use LaTex [ math]sqrt{x}[\math]

Why does [tex]sqrt{x}[\math] come out as [tex] not the formula? I have been struggling for hours . even typing in the tutorial example: [tex]x^2\sqrt{x}[\math] although the first expression was typed in as [ math ] (with out the spaces )
4. ### Least Squares Parabola

Hi all I have been trying to find the values of the coefficients for the least squares parabola: y = a + bx + cx^2 I have taken partial derivatives wrt a, b, c and now have three equations, but I don't know what to do next...any suggestions? Have you solved this before? thank you very much...
5. ### Latex & Mathbot

I am composing my latex in mathbot and copying the code into mathhelpforum. I insert before everything and after everything, but when I send it to myself (because I'm still working it out) all I get is the code. Any ideas why it's going awry?
6. ### Latex

I'm new to both this forum and to latex. How do I get my latex into a thread? I am writing in mathbot, but when I copy and paste, it's huge. Is there a way to type the code inside a thread so that I don't have to bother with resizing and copying and pasting? Thanks.
