The Integral of a function

The blue dashed line shows a function (which you can change by typing into the box at top left). The green line shows the integral of this function. A blue point is shown on the integral and the slope (tangent) at this point is equal to the original function. You can demonstrate this by dragging the blue point and noting how the red point, which shows the numerical value of the slope, follows the blue dashed line.
