Casio fx-CG50: Animation of a Graph
Introduction
You can easily animate a graph with the Dynamic Graphing mode. While I'm describing this procedure for the fx-CG50, I'm pretty sure it is available for the earlier models such as fx-CG10, fx-9750GII, and fx-9860GII.
Specifically, you can dynamically change a single variable between two points with a specified step.
For example: y = A*x where A varies from 0 to 5, and its step is 1.
General Procedure
1. Enter Dynamic Graph mode. On the fx-CG50, press [ MENU ], [ 6 ].
2. Type and select an equation. The equation can be a function, a set of parametric equations, a polar equation, or on newer calculators, a shaded inequality.
3. Press [ F4 ] (VAR) to take you to the variable screen. Select the variable you want to animate. You can animate any variable A - Z and θ. Keep in mind that X is used for functions equations, T is used for parametric equations, and θ is for polar equations.
4. Set the Animation Speed by pressing [ F3 ] (SPEED). The speeds that can be selected are:
F1: Stop & Go (you advance the slides with the right and left arrows)
F2: Slow speed
F3: Normal speed
F4: Fast speed
5. Press [ F6 ] (DYNA) to start the animation. To stop it, press [ AC ].
Example
x1(t) = 1.2 * A * cos T
y1(t) = A * sin (T + 1) * cos (π/(3*T))
with π/12 ≤ T ≤ 2 π, step π/12
