Notes
• The examples on the transparency masters
assume all default settings.
• Enter the function (expression) at the y=
prompt. Functions can contain stacked
fractions and most built-in functions such as
sine, cosine, e
x
, and so forth. Functions can
not contain n or the functions rand and
randint.
• To change a value on the table setup screen,
press - and then enter a new value.
• Depending on the function and the step
values, you may be able to affect the format
(decimal or fraction) of the y values. When a
decimal number (like 2.0) is used in the
function or the step values, answers can be
forced to decimal.
• To clear the table in ask-x, press J on
each entry.
• In ask- x , if you input a decimal, the x -value
displays as a decimal. For example, if you
enter 2À, the x -value displays 2À. If you enter
2.0À, the x -value displays 6.28319.
If you enter a fraction using q, the x-value
displays as a fraction.
• Press - to back up screens within the
function table.
• The TI-30XS MultiView™ calculator retains
the last entered function in memory when you
quit the function table application (%Q).
