Good calculus resource, could be better
I tutor calculus students for a living and this app is perfect for me - I know the material, I just can't remember all the formulas.
There is no interactivity. It's just a big PDF with a bunch of formulas and an occasional line of explanation. Beginners may frustrated in part because the organization is not great, but since it's free, you might as well have it.
The good news: there is a ton of stuff here, and it is all accurate as far as I can tell (exception: I can confirm an error in Simpson's rule that another reviewer pointed out). There is a sizable section on differential equations (including Laplace transforms), but not much on multivariable calculus.
Problem: there is a glitch with the headers. For example, when I was looking at derivatives, the header said "Algebra & Geometry."
The main complaint I have is that certain things have been overlooked. The derivative of an inverse function is missing. The section on complex numbers does not include Euler's formula. There's no mention of radius of convergence.
The list of power series expansions is too short - surely it should have cos(x), ln(x+1) and the binomial series. In the integration by parts section, why not include the tabular method? By and large, the list of integrals was shorter than I expected, but it does cover the basics.
It would be nice if this had a feature that allowed users to add their own notes (and corrections!).
But it's free, so you can't complain.
The reason I passed Calc!!
Great app, study tool, and reference guide.
Great app!!
This app is great for studying If you don't remember formulas or something basic but it'd be nice if it showed an example of the formula being put to use
