Interactive Definite Integrals
Things to Try
1. Visualizing the Area Under a Curve
Type f(x) = x^2 in the first box.
Then type int (which expands to an integral sign). Set bounds from 0 to 2, and type f(x) dx.
Desmos will automatically shade the area and calculate the definite integral value for you!
2. Dynamic Bounds with Sliders
Instead of numbers, type a and b as the bounds in your integral. Desmos will ask if you want to add sliders.
Click 'add all'. Now drag the sliders and watch the shaded area—and its calculated value—change dynamically!
