Graphically investigate the function

with a = 0 and for various values of x between 0 and 2p.


The following is an animation of such an investigation using the program Microcalc.

The animation shows the area bounded by the thin yellow line which is the graph of y = sin(t), the t-axis, and the line t=x for various increasing values of x. The thick yellow line is the graph of y = F(x), the area function.
