Tau is worse than Pi!
90 DEGREES is the FUNDAMENTAL ANGLE and PI/2 makes NAVIGATION SO MUCH SIMPLER!
1/2 a RA right! = 45 degrees to the right!
*******post from 2012******
SIN and COS still work on RADIANS
RA is my shorthand for Right Angle = PI/2 (in Radians)
1RA = 90/57 degrees/degrees = 1.57 Radians
So RA is usually in Radians but is not 1 RAdian.
RA is actually an angle, 90 degrees!
PI and TAU are too big for the mainstream to conceptualise as angles.
4 RA r = Circumference. ( 2 Pi r )
RA = Right Angle in RADIANS!
2 RA in a Triangle!
Get used to it! I'm programming the Nav Computers!
RA and Meters Northwards and Meters Eastward are the new units!
e.g. TOM: "Where is the nearest Servo?" NAVVY: "2 kilometres Northward and 700 meters Eastward" NAVVY: "Head 1 quarter RA Rightward from your current bearing" 1/4 RA = 90 degrees / 4 = 22.5 degrees! ****
