In this video, we provide essential "math help" by explaining how to "graph" "piecewise functions", moving beyond simple ...

Here's the new description with all links and additional text removed: Learn how to graph piecewise functions. A piecewise function is a function which has more than one sub-function for different sub ...

That is clearly not in line with the laws of physics unless you have no mass. So, although the piecewise-linear graph can be a pretty good approximation to real life, in real life no person would ever ...
