Formulus Free App Reviews

Great app, love it. FYI, theres a mistake in the power series expansion. For cos(x) you used cosh(x) which is not the same. The power series expansion for cos(x) is an alternating series, on the other hand, cosh(x) is the power series of cos(x) but you have to take the abs value of each term (not the same as abs val of the whole series). I just wanted to point out that typo.

Good app but the cross product entry is wrong.

Not worth the time it took to download. Try Google.

The app seems great and has a lot of useful information, but it doesnt seem to be completely compatible with the larger iPhones. The screen size is a little bit obnoxious.

The simple app has all equations in all mathematic subjects.

Its an amazing app to use for study guide and to expand my mind in the mathematic field!! Absolutely love it!

Very handy and convenient for my Calc 1 class. It beats looking back through pages of notes by far!
