Pretty dang awesome

Amazing app! I think it would be even more beneficial if what the variables stand for is included with each formula. Great job nonetheless!
Awesome!

This app is really helpful when trying to remember the properties of different figures. It will definitely come in handy while studying for finals!
Calculus derivative formulas are wrong

The tan and csc give the wrong answers. I'd like this app if I wasn't worried about mistakes.
inaccurate formulas
jjeenn
was using to review my trig identities and some are wrong- for example- in the product to sum category one of them is wrong (to difficult to type here) but has sin(a)sin(b) twice with different formulas - one with the formula for sin(a)cos(b) I know I saw another one that was wrong but since I don't actually have them completely memorized assumed I had it wrong- I have a test in Thursday- thank goodness I know them well enough to spot these error before memorizing them all wrong.
Good but with one problem

Conceptually, this is a very good idea for an app. However, speaking as someone who has as much trouble remembering what all the variables stand for as the formulas themselves, I would get much more use out of it if I didn't have to have a second reference to help me remember what "k" represents in a particular equation. Just replace the variables in your equations with the components they represent, and this truly will be a one-stop-shop for formula recollection. Remember, it's more important to know what a variable represents than to use the "correct" variable for a specific value.

This is a great app, exactly what I was looking for. But it would be really nice if the calculus equations had things in terms of "u". Because a lot of the formulas include the derivative of u but you cant tell on this app.
Great App

Great App with plenty of useful formulas, I just wish that there was a key that gave all the variables and said what they stood for.
