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 FunctionThis 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 = 2x 2 – 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:
(3)Press Eto store the expression.
uTo 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 wto 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
(3)Tap the box to the right of line number “yt3”, and then input the
9dct)w.
