Hello Bill,

Draw a sine wave going from, say, 0 to 2Pi. We know that a sine wave is based on a unit circle so the Y axis can go from 1 to -1.

Number the y axis as .25, .75, 1 and the negative values.

Supposing a student is asked to identify the degree or radian angles of 0.5 and draws a line parallel to the x axis. This will show the sine wave being crossed at various places. On paper the student would drop a perpendicular from the crossing point to the x axis and see that sin 0.5 = 30deg etc. They can then see other angular values that apply to 0.5, or any other value between -1 and 1.

This, of course applies to the cosine etc as well.

I thought this may be relatively easy but is beyond my knowledge at the moment.
