👉 Learn how to graph piecewise functions. A piecewise function is a function which has more than one sub-function for different sub-intervals (sub-domains) of the function's domain. To graph a ...

In this video, we provide essential "math help" by explaining how to "graph" functions, beginning with a basic cosine wave ...

Some students do this by arguing that the graph from t=0 to t=60 is essentially linear already; that tiny bit of curvature we see is so small it can be neglected, so just find the slope of the “line” ...
