kShading the Region Bounded by Two Expressions

You can shade the region bounded by two expressions by specifying [ShadeType] as the function type and then inputting the expressions in the syntax shown below.

Syntax: ya{lower function f(x), upper function g(x)} A < x < B The value of B must be greater than A.

•A < x < B can be omitted.

•A < x < B can be replaced with x > A.

•A < x < B can be replaced with x < B.

Example: To graph f(x) = x2 – 1, g(x) = –x2+ 1, –1 < x < 1

uClassPad Operation

(1)On the Graph Editor Window, tap [Type] and then [ShadeType].

(2)Store ya{ x2–1, –x2+1} –1<x<1 in line y1.

(3)Tap $.

•When [ShadeType] is selected as the function type, the status bar displays “{low, upper} L<x<R”.
