Chapter 2: Operating the Graphing Calculator
Do not type out math figures ( sin , log , etc.), graph equation
names (Y1, Y2, etc.), or list names (L1, L2, etc.), etc. with A
keys. If "SIN" is entered from A mode, then each alphabet
character — "S", "I" and "N" — will be entered as a variable. Call
up the figure and equation names from within the second func-
tions and various menus instead. If a colon (:) is used, data may
continue to be entered in more than one term.
