Upper Sum, Lower Sum, and Definite Integral
Approximate the area under a curve between A and B with Upper and Lower sums.
Use the slider to change the number of panels in the approximation. Use check boxes to turn Upper Sum, Lower Sum, and Integral on or off.
Drag points A and B along x-axis to change the limits/bounds.
Modify the function, f(x), by dragging the curve to the left, right, up or down or writing another function for f(x) in the Input Bar at the bottom.
