Is there a Copy-and-Paste List of Popular Math Formulas?

Math equations in Wikipedia articles are written in LaTeX. Wikipedia is easy to search and likely has all of the equations for an intro stats class.

For example, if you want the equation for sample standard deviation you could navigate to the relevant Wikipedia article (here), go down to the section that has the relevant equation, then click on "edit" to see the LaTeX code for the equation. For this example, the equation for sample standard deviation is given as s = \sqrt{\frac{1}{N-1} \sum_{i=1}^N (x_i - \overline{x})^2}.

With all of these steps, it would probably be faster to just write the LaTeX equations by hand; this depends of course on the specific equation.

• Try http://www.equationsheet.com/, it is not exhaustive but it has some search capability.
• NIST Digital Library of Mathematical Functions http://dlmf.nist.gov/ has all its mathematical formulas and identities encoded in TeX form which can downloaded and copied.

Web equation is a good resource for math teachers designed for copy and pasting. Click on the garbage can to clear the screen and then write your formula/equation; the formula gets built in the bottom left hand corner. You can also undo/redo mistakes with the arrows at the top lefthand corner. When the formula is correct, highlight the LaTeX code in the bottom righthand corner and copy/paste into your document. Since equations are in math mode, you will need to paste in between $ signs.
