Core Concepts
Derivatives
Explore how derivatives represent rates of change. Drag a point on the position graph and watch the speed graph update in real time.
Fundamental Theorem of Calculus
See the Fundamental Theorem of Calculus in action: the area under the speed curve equals the distance traveled, and the derivative of distance gives back the speed.
Integrals
Explore integrals through rainfall accumulation. Adjust the time interval and watch the area under the rate curve translate to total accumulation.
Limits
Explore limits by watching how the secant line approaches the tangent line as two points converge. Drag the slider to shrink the interval.
Volume of Revolution
Create a 3D vase by rotating a profile curve around an axis. Adjust the profile points and orbit to view from any angle.
