Using Math Actions
Math Actions are available on Notes and Calculator pages.
When you display the context menu for a selected expression or equation, the menu may include a Math Actions submenu that lists the available actions. Each action might prompt you for any needed parameters.
The specific math actions listed depend on:
• | The type of expression or relation. |
• | The operating system in use (numeric or CAS). |
Example of Math Actions in Notes
1. | Insert a math box, and type the equation x2+3x+1=0, but don't press Enter yet. |

|
2. | Tap the equation to display its context menu, and select Math Actions. |
|
|
3. | Select the action to perform: |
- | Solve Numerically for numeric OS. |
- | Solve for CAS OS. |
You are prompted to enter parameters. For example, Numeric Solve prompts for the variable of interest, initial guess, lower bound, and upper bound.
4. | Type a value for each parameter. When options are available, you can tap an arrow to make a selection. |
