13-5 Dynamic Graph Application Examples

With the initial velocity defined as V and the angle defined as θ , the parabolas can

be obtained using the following expressions.

1. Input the functions, making sure to specify

2. Display the coefficient menu and specify the dynamic coefficient.

3. Display the coefficient range menu and specify the range values.

4. Start the Dynamic Graph draw operation.

Example

To use Dynamic Graph to graph the parabolas produced by

balls thrown in the air at an initial velocity of 20m/second, at

angles of 30, 45, and 60 degrees. (Angle: Deg)

Use the following View Window parameters.
