A few mistaken formulas away from 5 stars, but a lot better than free alternatives!

First, it doesn't have very many chemistry formulas. Second, it's 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...

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.
