Use Desmos to investigate the beautiful world of integral calculus. Simply type int to get started. Then fill in the lower bound, upper bound, and the integrand and you’ll be on your way! Evaluate a definite integral in an instant, or plot an integral with varying bounds. Get started with the video on the right, then dive deeper with the resources and challenges below.

If you'd like to explore the graph shown in the video (including taking a look at what's inside the "visual" folder), click here.
