Copy of How to Enter Algebraic Input
Create new objects
You may create new objects by either using the Graphics Tools provided in the Toolbar, or by entering their algebraic representation into the Algebra Input and pressing the Enter key.
Note: Each object ist representet graphically in the Graphics View and algebraically in the Algebra View, no matter how it was initially created.
| 1. |  | Select the Point tool from the Toolbar and click in the Graphics View to create a new point. |
| | B=(2,1) | Enter B = (2, 1) into the Algebra Input and press Enter in order to create a new point. |
| 2. |  | Select the Line tool from the Toolbar and click twice in the Graphics View or on two existing points to create a line. |
| | Line(A,B) | Enter Line(A, B) into the Algebra Input and press Enter in order to create a line through the two points A and B. |
| | y = 3x + 1 | Enter the linear equation y = 3*x + 1 into the Algebra Input and press the Enter key. |
| 3. | f(x) = x² + 2 | Enter the function f(x) = x^2 + 2 into the Algebra Input and press the Enter key. |
