Drawing f (x) Type Function Graphs and Parametric Function Graphs

Drawing a Parametric Function Graph

Example: To graph {xt = 3sin(t) + 1, yt = 3cos(t) + 1} and {xt = sin(t) − 1, yt = cos(t) − 1} (Angle Unit Setting: radian, 0 <t <2π)

uClassPad Operation

(1)Tap the [Graphs] tab to display the general graph editor.

(2)Confirm that “Rad” is displayed as the angle unit setting on the left side of the status bar. If it isn’t, tap the angle setting until “Rad” is displayed.

•For details about the information that appears in the status bar, see “Differential Equation Graph Application Status Bar” on page 14-1-8.

(3)Tap [Type] - [Parametric] or the gtoolbar button.

(4)Input the expression for each graph, and (0 <t <2π) for the range of t.
