From GeoGebra Manual
Creating Dynamic Worksheets
In this activity you will learn how to create a dynamic worksheet that illustrates how lower and upper sums can be used to approximate the area between a function and the x-axis.
Preparations
- Open a new GeoGebra window.
- Show the Algebra View, Input Bar and coordinate axes (View Menu).
Construction Steps
| 1 | Enter the cubic polynomial f(x) = -0.5x³ + 2x³ – x + 1 | |
| 2 |  |
Create two points A and B on the x-axis Template:Hint: These points will determine the interval. |
| 3 |  |
Create a slider for the number n (interval 1 to 50; increment 1) |
| 4 | Create uppersum = uppersum[f, x(A), x(B), n]  Hint: x(A) gives you the x-coordinate of point A. | |
| 5 | Create lowersum = lowersum[f, x(A), x(B), n] | |
| 6 |  |
Insert dynamic text Upper Sum = and select uppersum from Objects |
