Reply To: Y1
Laurie, our recommendation is that the Graphing Calculator Guideline section you quote (6.1) applies only to material shown in a screen. When an expression such as the letter-number combination Y1 appears in the text (not the screen), it is transcribed in Nemeth. A dot 5 between the Y and the number 1 will indicate that the number is printed on the baseline and not in the subscript position.
