Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points).

In this video we will explore how to create the cosecant graph using the unit circle and sine graph. We will then detail the characteristics of the cosecant graph that make it different as well as ...

We continue to insist that our population spend years trying to learn how to calculate by hand - solving equations, multiplying matrices or sketching graphs - instead of focussing on how to ...

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those ...
