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 them a parametric (Param) type.
2. Display the coefficient menu and specify the dynamic coefficient.
3. Display the coefficient range menu and specify the range values.

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)
