Question 647906: Suppose 90degrees < theta < 180degrees. Determine with reasons whether each of the following is positive or negative.
A. tan(theta + 180degrees)
B. cot (theta/2)
C. sec (-theta) Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! Suppose 90degrees < theta < 180degrees. Determine with reasons whether each of the following is positive or negative.
..
A. tan(theta + 180degrees): negative
This moves the standard position of theta from quadrant II to quadrant IV where tan<0
..
B. cot (theta/2): negative
Theta remains in quadrant II where cot<0
..
C. sec (-theta): positive
Theta is in quadrant IV where sec>0
