Practice a graph-canvas graph on the Classic Graphing 84

Send the graph to the Classic Graphing 84 and watch the exact key presses, so you can do it on the calculator your exam allows.

Open in Trident

1. Open Menu › Show on the calculator.
2. The sheet lists the Y= lines the Classic Graphing 84 will get. Sliders are sent as their current numbers.
3. Tap Watch the key presses to see every key pressed on the real keypad, step by step: Y=, each function, the WINDOW values and GRAPH.
4. Tap Open in Classic Graphing 84 to switch to the calculator with the same graph already drawn.

Tips

• The handheld graphs one kind at a time: y = lines, polar r = lines or parametric curves. Other lines (inequalities, x² + y² = 25, tables) are listed as skipped, with the reason.
• Trident is for practice only and is not an approved exam device.
