They know of the unit circle with hypotenuse as 1.
They then blunder, and blunder badly for they spuriously assign 180 degrees to be 3.14.... Why why assign 180 degrees as 3.14... when you already defined sine as opposite/hypotenuse with unit circle forcing 180 degrees to be 2, since 90 degrees is 1 of unit circle.
Is it that all three of you are deplete of Logic, have no logic, never formally studied logic. Yet you inflict your nonlogical habits onto young students.
If you had had just a gram of Logical intelligence could see that the unit circle forces sine to define 180 degrees as being a diameter of 2. Thus making the sine graph and cosine graph to be a SEMICIRCLE graph.
So, Andrew, John, why not do things in math LOGICALLY, not some bozo whim of yours.
Burse, Wiles, Conway-- more than 30 years now of this NO LOGIC nonsense fed to the world of math

I would rather resign as a math teacher than teach another classroom that a sine is sinusoid.
I respect the truth, more than a lie in front of young students.
