Storing Functions

uClassPad Operation

(1)On the application menu, tap T.

(2)On the Graph Editor window, tap the down arrow next to “y =”, or tap [Type].

(3)On the list that appears, tap the function type you want to select.

Storing a Function

This section presents a number of examples that illustrate how to store a Graph & Table application function.

uTo store a rectangular coordinate function (Y=)

Example: To store the rectangular coordinate function y = 2x2 – 5 in line number y1

(1)On the Graph Editor window, tap [Type] and then [y=Type] to specify a rectangular coordinate expression.

(2)Tap the box to the right of line number “y1”, and then input the expression:

2x{2-5.

(3)Press Eto store the expression.

uTo store a polar coordinate equation (r=)

Example: To store the polar coordinate equation r = 5sin3  in line number r2

(1)On the Graph Editor window, tap [Type] and then [r=Type] to specify a polar coordinate expression.

(2)Tap the box to the right of line number “r2”, and then input the expression: k9fTsd8).

(3)Tap w to store the expression.

uTo store parametric functions

Example: To store the parametric functions below in line numbers xt3/yt3 xt = 3sint

yt = 3cost

(1)On the Graph Editor window, tap [Type] and then [ParamType] to specify parametric expressions.

(2)Tap the box to the right of line number “xt3”, and then input the x-expression: k9dTst)w.

(3)Tap the box to the right of line number “yt3”, and then input the y-expression:

9dct)w.
