Hi,

First of all congratulation for Smath. This is the ONLY true MathCAD-like software i have found online.Clap

I have used it only 5-6 times but looks to be a very useful software.
The strange bug you see in the subject is in the image:

Bug report

You can see something wrong in "sin" function; "cos" works good.

I'm not sure this is a bug or there is mistake in my function definition.
I discover this because I was defining a non continuous function like

f(x)=sin(x) if x<=0
f(x)=cos(x) if x>0

As a request for future version, function definition with if istruction (like in MathCAD).

Thaks.

At the end a little question (if it's not too much indiscreetBlush ) why freeware but not GPL; I think You can find someone interest to help you in software develop.

Thanks Again. BYE BYE

Hello. Thank you for the report!
This is a bug in symbolic library found. Sorry for this. I've just fixed it, so here is the results of yours calculations:


I have created a new version of dll for you, so you can replace SyLib.dll file (usualy located in C:\Program Files (x86)\SMath\SMath Studio) with a new one from here.

In future, freeware will give me easier way to earn (besides open software). Anyhow I hope so Good

Thank you.
