Graphing with restricted domains CLASSPAD help

[crunk]

If i were to have a function which has 2 restricted domains eg
(-pi, pi) U (pi, 3pi)

Would it be possible to graph this on the classpad in graph and tab?
Normally I would use |  -pi    less than   x     less than  pi           
I can do it for the single domain but i can't work out the syntax for the second.

Does anyone have any ideas?

If you've got the latest operating system in the 2D menu there's a hybrid function button you can use. You just have to put in the equation twice (or more), each with the required domain, then drag it onto the graph. Otherwise you could do it in graphs, by also typing in the same equation in more than once, each with separate domains.

Thank you, thought that was the only way to do it.

Yeah, i tried to find another way a while ago but couldn't find anything, so I just use this method. Doesn't really take that much longer than it otherwise would.
