I think they're just multiplying the families together. It also works with parentheses or even multiplication (so Y1=(X<2 and X>7)(X²) would also work). Braces are used to graph a family of functions, like Y1=X^{1,2,3,4,5}.

Also, using braces allows you to have a nearly unlimited number of functions.

Yep, you can. Not sure about X=, though...

X= does work, X=4 was the first I tried actually

I meant I didn't know if X= supported function families.

:O, like X=2Y,

Nope, you still can't do that in Inequalz. It only allows you to input constant functions for X, like X=5.

:O I can mix curly braces with Inequalz then

But not with X=. If you input X={1,2}, it gets cleared, unfortunately.

But 6 different vertical lines should be enough

Exactly what I mean, mix Inequal with Curly Braces system

What? It doesn't work in the screenshot...

What are you talking about?

Using Y you can, in my calculator you can have Inequal installed and use Y to do {X=2Y}

Um ... still doesn't work. How are you doing it? Could you post a screenshot?

AHhaha, just tried it: it doens't work. I confused '=' functions with '>' and '<' functions.

Sorry :s

Have you tried > or < either? IIRC you can't have any Y= equation with Y inside, no matter what extra graphing app you have installed. It wouldn't work anyway since it's not a function. And X= only takes single constant values. If you want to graph a complete X= equation, use DrawInv . It doesn't actually make a graph that you can trace and do other stuff with, unfortunately
