      Hi. I am struggling to understand a key on the graphing calculator.

      X,T,0,n (only the zero has a horizontal line in the center. What does this 0 stand for and how should it be brailled in this instance.

      I have researched a bit on the internet and it seems to stand for a "polar coordinate" in a couple places. It is also described as being the Greek theta in some instances. I just wonder how I should be brailling the "0" with the horizontal line in center.
      Thanks,
      Patty

        Without seeing your print, I would say the zero with the horizontal line is a Greek theta. We often come across this calculator keystroke and I've always seen it as a theta.
