Graphing Circular Functions

The following file is for year 12 students covering trigonometric functions sine and cosine. It presents an orderly method to graph functions of the form:

f(x) = a sin[n(xh)] + k, x₁ ≤ xx₂ or f(x) = a cos[n(xh)] + k, x₁ ≤ xx₂. It assumes knowledge of trig functions (or circular functions) and how to use the unit circle.
