u ClassPad 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.
u To store a rectangular coordinate function (Y=)
Example: To store the rectangular coordinate function y = 2 x 2 – 5 in line number y 1
(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 “ y 1”, and then input the expression:
2x{ 2-5.
(3) Press E to store the expression.
u To store a polar coordinate equation (r=)
Example: To store the polar coordinate equation r = 5sin3
θ in line number r 2
(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 “ r 2”, and then input the expression:
k9fTsd8).
(3) Tap w to store the expression.
u To store parametric functions
Example: To store the parametric functions below in line numbers xt 3/ yt 3
xt = 3sin t
yt = 3cos t
(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 “ xt 3”, and then input the x -expression:
k9dTst)w.
(3) Tap the box to the right of line number “ yt 3”, and then input the y -expression:
9dct)w.
