Gegevens invoeren en objecten ccreëren
In het Rekenblad van GeoGebra heeft elke cel een specifieke naam.
Voorbeeld: De cel in kolom A en rij 1 heet A1.
Met de cellen van het Rekenblad kan je objecten creëren die getoond worden in het Tekenvenster(b.v. punten).
Task 1
| 1. | A1 | Enter the number 10 into cell A1.
Hint: Always confirm your input by pressing the Enter key. |
| 2. | B1 | Enter the coordinates (-2, 2) into cell B1.
Note: The point B1 = (-2, 2) is automatically shown in the Graphics View. |
| 3. | 
| Select the Move tool and drag point B1 in the Graphics View. Note: The Spreadsheet View shows the current position of point B1 in cell B1. |
| 4. | 
| Delete the content of cell B1. |

Cell references
You may refer to another cell by using its name in your new input.
Note: If the content of this cell is modified, the new input adapts automatically.
Task 2
Task 3
| 1. | A1 | Change the number in cell A1 to 1.5 and confirm your input. |
| 2. | B1 | Enter the formula = 2 * into cell B1 and then select cell A1 in order to insert its name into the formula. Confirm your input.
Note: GeoGebra calculates 2 * 1.5 and displays the solution 3 in cell B1.
|
| 3. | A1 | Change the content of cell A1 to 3. Note: The content of cell B1 automatically adapts to your changes. |
| 1. | C1 | Enter the coordinates (A1, B1) into cell C1 and confirm your input.
Hint: Cell C1 now shows the coordinates (3, 6). The corresponding Point C1 is automatically displayed in the Graphics View. |
| 2. | A1 | Change the value of cell A1 to 2.
Note: The coordinates in cell C1 and the corresponding point automatically adapt to your changes. |
