Instructify

Sure, you know Pythagoras and his famous theorem, but do you know Planck’s Quantized (Quantum) Energy Equation? Probably not. EquationSheet.com is a great resource for math and science equations, all in a searchable and simple database that allows you to collect and sort through all your favorite equations. Calm down, I know this is exciting, but there are more Algebraic, Geometrical, and Trigonomical expressions, definitions and theorems than you can shake a stick at here.

If you’re teaching any of these subjects, you probably know more about this stuff than I do, so you might know what to search for more easily. If you are a real equation aficionado, you can even register for your own free account and compile your favorites in one easy-to-find location. If you are longing for some constants, equations or SI units, you can visit this site for all sorts of fun. Hopefully, things might make a bit more sense to you than me – I was an English major. –JEREMY S. GRIFFIN
