Using Shading Patterns to Differentiate Functions
When you select ¾ (shade above) or ¿ (shade below) for more than one function, the TI
-86
rotates through a series of four shading patterns.
♦
First shaded function: vertical lines
♦
Second shaded function: horizontal lines
♦
Third shaded function: negatively sloping diagonal lines
♦
Fourth shaded function: positively sloping diagonal lines
The rotation returns to vertical lines for the fifth shaded function and repeats the order.
In the example,
¾
(shade
above) is selected for
y2
. All
window variables are set to
the default values (page 82).

If you assign
¾
or
¿
to a
function that graphs a family
of curves (page 86), the
same pattern rotation applies
to the members of the family
of curves.
