User reviews

Definite Integrals only….

I had hoped that this would have a CAS component, so that if I told it to integrate cosxdx it would reply sin x + C, but it will not do indefinite integrals. Hopefully the authors will include a CAS in later upgrades.

A great start!

This calculus app is a great beginning. Very straightforward and uncluttered. I think many student will benefit from this calculator. It would be an educational improvement if Chrisoft would also show the solution's steps. Or... Have a way for the solvers to work thru the solution themselves.
