We should now be able to draw a diagram showing machin's setup. 1. draw a unit circle 2. draw a line from the origin at 45° to the c-axis. 3. add a line tangent to the circle at the point (0,1). 4. draw a line from the origin at angle whose tangent is 1/5. 5. draw similar lines for angles 20 and 40. if your diagram is accurate, you should see that the lines for 40 and 45° are quite close. how does this relate to task 11?
