I was taking notes in a math class and found it difficult to type in symbols such as Greek letters, operators etc. It was tedious to open a web page or pdf, find the symbol, copy it and enter it in my notes. So I threw together this page that tries to make it a bit easier to find and grab some common math symbols. The copied symbols are utf-8 encoded. (if you can take notes in Latex, you don't need this)
To use this page, just type in a few letters describing what you want and it will pop up any matching symbols. The symbols are displayed in a textarea so you just need to click on it and it will copy it to the clipboard
Examples : 'arrow', 'e', 'ep', 'diff','floor'
