Hi ! Today, I input a function in "Conics" .That was "y^2=x^2" .But CP300 drew it wrong ! CP300 drew this function : "y=?2X" . I don't understand. Can you help me ? (I'm Sorry for my English! )

Perhaps it's a bug with an earlier OS version.. go to classpad.net and update it (if you haven't yet done so)

I think that it's a problem in CP300's software!
I tested it on "ClassPad Manager". But there is no deffrence between CP300 v1.24 and ClassPad Manager v1.24 .
It's correct : y^2=x^2 => y=?x
But It isn't correct : y^2=x^2 => y=?2x
I waiting for your opinion ! Please tell me it soon ...

You're right, there's a bug in the drawing of the graph...

It creates a valid expression for it ( (x-y)(x+y)=0 ), and the graph solve functions work correct as well, but the drawing is wrong :/

We'll have to add it to the bugs list.. weird stuff
