Using Tables

*

1

An error occurs if a graph for which a range

is specifi ed or an overwrite graph is included
among the graph expressions.

*

2

The number table is generated only for the

function type specifi ed on the relation list
(Table Func). You cannot generate a number
table for a mixture of different function types.

The function type specifi ed in the GRAPH mode

is not one of these three, entering the TABLE
mode causes the function type to change to
rectangular coordinate (Y=).
