Question about Texas Instruments TI-89 Calculator
When I graph y = square root of x, or cube root of x, or any root of x, I get an error message saying undefined variable. I don't understand this.
I have a TI-89 Titanium and I have experienced the same problem. HERE IS HOW TO FIX IT:
Goto " MODE " and scroll down the options until you get to
" COMPLEX FORMAT " change that option to " RECTANGULAR " and press ENTER until you exit out of the " MODE " screen. (very important that you press ' enter ' until you exit because if you don't, it will not save your changes. )

I had the same problem, when the term under the root could be <0 the complex mode can't be polar. Changing to another mode graphed it.
