Tangent is positive in Quadrant 3 (ASTC as I learned it), so wouldn't sine be negative there?
I asked my dad about this too and he said that the answer is B. but I don't understand because 7\pi/6 is in the third quadrant and isn't that negative if it's sine?
[SOLVED] Solving csc x + 2 for 0
"Solve csc x + 2 = 0 for 0 <= x < 2 \pi
A. \pi/6 and 5\pi/6
B. \pi/6 and 7\pi/6
C. 4\pi/3 and 5\pi/3
D. 7\pi/6 and 11\pi/6
csc x =2
sin x = 1/2 = 30 degrees = \pi/6
