After Geoff Hitchcox found Fred Sawyer’s Error in a Misplaced Dial paper, I used Sawyer’s equation (8) to check a few points on the graph you had posted two days earlier. They matched exactly. I’ve wondered ever since how you determined the plotted points. If it’s not too much trouble, I’d like to see the trigonometry sketches you offered to post.
