Find the reference angle for each. Define what a reference angle is. Do not just give the answer.
(1) 1000 degrees
(2) 5pi/4
(1) 1000 degrees
(2) 5pi/4
-
1) 1000 = 2(360)+280 = 280 degrees lies in quadrant 4 and the reference angle is 80 degrees
2) 5pi/4 = pi + pi/4
The reference angle is pi/4 and lies in quadrant III
2) 5pi/4 = pi + pi/4
The reference angle is pi/4 and lies in quadrant III
