| 1. Change Graph Type to Parametric |
Press MODE key |
 |
| |
Press right arrow key |
 |
| |
Press 2 for parametric |
 |
| 2. Save New Settings |
Press ENTER |
 |
| Let's graph the parametric equations: x = t + 2sin(2t), x = t + 2sin(5t) |
| 3. Input Equations |
Press DIAMOND key, then F1 key |
 |
| |
type x function into xt1 |
 |
| |
type y function into yt1 |
 |
| 4. Graph |
Press F2, then 6 (for ZoomStd) |
 |
| Note the direction the curve is drawn – from initial point to terminal point. |
| NOTE: To trace, use left/right arrow keys. |
| To change restrict the values of t: |
| 5. Change Window |
Press DIAMOND key, then F2 (for WINDOW) |
 |
| |
Change appropriate values |
 |
| |
Press DIAMOND key, then F3 (for GRAPH) |
 |
| To evaluate the equation for a particular value of t: |
| 6. Evaluate |
Press F5 |
 |
| |
Press 1 (for Value) |
 |
| |
Type in value for t, then ENTER |
 |
| In this case, the point on the curve when t = 6 is (4.92685, 6.3085). |
