What is the reference angle for 13(pi)/3? What is the reference angle for 7(pi)/6? What is the reference angle of theta if theta = -382.1 ^{circ}? What represents the reference angle for 3(pi)/4? How to find a reference angle ...
So, what is a reference angle? A reference angle is the measure of the smallest positive, central angle whose rays are the terminal side and the x-axis. The reference angle on the unit circle can be measured in either degrees or radians....
3. If angle A is in quadrant III then the reference angle A r = A - 180° if A is given degrees and A r = A - π if A is given in radians. 4. If angle A is in quadrant IV then the reference angle A r = 360° - A if A is given degrees and A r = 2π - A ...
Okay, this is in radians. So I'll need to think in terms of 0 radians and 2π radians for the positive x-axis, and π radians for the negative x-axis. The angle they've given me is radians. Doing the division to convert the fractional form to decimal form (and ignoring the π ...

Each source has configuration that determines how to map the raw value provided by the device into a rotary angle. cpr is the number of counts per revolution, offset provides an integral count offset, and sign can be used to invert the reading. The final reading is (raw + offset) * sign...
