Area Under A Curve

Visualization of the area under a curve

The GUI provides an interface to visualize and compute the area under a curve. Given a function f(x), also called a curve of a real variable x and an interval [a, b] of the real line, the integral is equal to the area of a region in the xy-plane bounded by the graph f(x), the x-axis and the vertical lines x = a and x = b.
