iFormulas App Reviews

First, it doesnt have very many chemistry formulas. Second, its great....if you already know the name of the formula you need and what all of the variables stand for.....

I would love another category: statistics! Thing like standard deviation (sample vs. population), chi square, variance, etc...

But maybe put in like practice problems to apply the formulas

Look at those functions

Hi...I go to school with the creator...bye

A very useful app, however there is a mistake in the list of common derivatives, it lists d/dx csc(x) = secxtanx when it should be equal to -cscxcotx.

Awesome app! TONS of formulas for many different things

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

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

Brendan winter thank you so much

The tan and csc give the wrong answers. Id like this app if I wasnt worried about mistakes.

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 dont 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.

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 didnt 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, its more important to know what a variable represents than to use the "correct" variable for a specific value.

please add iphone 5 support and get rid of horizontal scrolling

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

Almost all equations youll need
