Looking over Lesson 17
This from Degrees and Radians is first step in wrong direction:
This system that puts 0 Degrees in North Direction will go against all the Basic Trig functions specially _ATan2 that has 0 degrees in the East Direction. I have already provided 2 visuals for the actual positioning of degrees and directions.
And in all due respect this visual:
Is a freak'n nitemare! No wonder that guy is confused
To move from point 1 = x1, y1 to point 2 = x2, y2
dx = x2-x1
dy = y2-y1
Angle = _Atan2(dy, dx) in radians
to normalize we use
d = _hypot(dx, dy)
Vx = dx/d x component of vector
Vy = dy/d y component of vector
Drawing Regular Polygons with different number of sides is excellect teaching device for Sin and Cos.
I will make up a lesson for you. Wait maybe you @TerryRitchie already have that somewhere?
