A Step Function That Jumps Once and Drops

2014-07-25 10:55
This applet demonstrates f(x) = (x/|x| + (1-x)/|1-x|) / 2, which equals 1 on [0, 1) and 0 elsewhere. It shows how to construct a step function using absolute values and division, and provides an equivalent definition using the If command, aiding in understanding piecewise function graphing.
