(uni)quation

Uniquation is designed to search for mathematical information on the Internet.

To find an information about some mathematical object you should enter its representation in TeX format and press ‘Search’.

To use uniquation search system, you should know how to write down formulae in TeX. It is a popular format that is used by wikipedia and mathematical sites on the Internet. You can learn its basics in 25 min by using this interactive course .
