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.
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.
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.
