I have a Casio fx-9750GII, I'm starting to get to grips with just how useful it can be. For those familiar with it you will be aware it can graph functions.
However I noticed when looking through the set up menu it has a complex mode which can be set to a+bi. So I enabled that option and entered 3+4i as a function, the calculator does not draw anything.
How do I graph complex numbers?
