This page aims to offer information on how to use SearchOnMath. Our tips relate basically to keyboard functionalities for inputting the mathematical formulas to be searched.

SearchOnMath uses the TeX (or LaTeX) language for mathematical expressions. If you already have a formula in this format, all you have to do is paste it on the search field. You'll see that the formula is rendered in the field right below (we use MathJax for rendering). If an error occurs in the rendering phase, go back to the TeX/LaTeX expression and make sure that the portion causing the error is fixed. If you find no mistakes despite the problems in rendering, you may go ahead and proceed with the search anyway.

We've developed the keyboard with the main mathematical symbols to assist you in assembling formulas. The symbols are organized into the following tabs:

- Here we have a selection of the most commonly used symbols contained in the other tabs. You should be able to assemble a great variety of formulas using only this tab. Pay special attention to fractions, which should preferably be written using \frac (obtained through the button ). If possible, avoid using the symbol / for this purpose.
- Operators and functions widely used in Calculus appear in this tab. Some examples are summation, limit, and integral. A tab can also contain an extension button leading to less common elements.
- Relational operators.
- Arrow operators.
- Greek letters.
- Set operators.
- Trigonometric functions and other operators related to Geometry.
- Logical operators.
- This tab brings up a wizard for setting up matrices and systems of equations.
- Ceiling and floor functions, dots, etc.
- A mix of more specific operators and functions, some closely related to the areas of Physics and Chemistry.

The results page follows the pattern of a traditional search tool: formulas similar to the one you searched, a preview of the pages where they appear, and links to access those pages (by clicking on the titles).

The keyboard gets retracted when results are displayed in order to enhance visualization. If you want to work on a new search, simply move your mouse over the search field. This will make the keyboard re-expand.

Want to search using a formula from the results page?

Very easy: Just move your mouse over the desired formula, and a button for this search will pop up. :)

Well, that's it. You're ready to start using SearchOnMath.com. And don't forget to visit our pages on the social networks for weekly new posts with fun facts about the world of Mathematics!
