[BlindMath] Drawing trigonometric Functions and their Graphs

[Bill Dengler]

What sort of class is it? As in, can the skills be tested non-visually? For example, to find mins and maxes you could differentiate the function and show that way (zeros/x-intercepts of the derivative). Same if you need to show concavity/inflection points (second derivative).
You could then, say, find the period length and state both extrema, increasing/decreasing trends, and where (x, y) the graph increases/decreases.
