You can put this solution on YOUR website!
evaluate csc(theta) if cos(theta)=1/2 and tan(theta) is negative
The cos is positive and the tan negative in the 4th quadrant
The reference angle is 60 degrees; 300 degrees in the 4th quadrant
csc(300)=-[2sqrt(3)]/3
A) 2 (square root symbol)3/3
B) -2 (square root symbol)3/3
C) 2
D) -2
