Hi, I was just playing with the software and it looks promising, but I cannot say that it is reliable right now. While checking out differentiation option I found an error. On the screen you can see 3 different calculations and second one gives wrong result.

Hello there,
You did a great piece of work here, and I think I found out a problem.
Sorry but I can't post an image of it.
I compute the following
derivative of (exp(1/x)) and derivative of (exp(x^-1)) I'm expecting the same output but I got for the first one :
-exp(x)/x^2 and for the second one -exp(1/x)/x^2.
The version I'm using is windows 0.78 b3347 and I reproduced it also on the handheld version.
Thanks in advance,
C.
