The area between a curve and the x-axis is found by integrating the function. This interactive shows the relationship between the area and points on the antiderivative function.
- Input a function. View the graph and the graph of its antiderivative.
- Move points a and b to see the change in area.
- Notice the area is found from the difference between points on the antiderivative curve. It illustrates how the integral relates to the antiderivative function.
