Question

find csc(2pi/3)

Answer 1

csc (2pi/3) = 1/sin(2pi/3)

Answer 2

sin (2pi/3) = sqrt(3)/2 from unit circle

Answer 3

so 1/(sqrt(3)/2)) = 2/sqrt(3)

Answer 4

csc is basically 1/sin so you would basically find sin of 2pi/3 and flip it...so your answer would be 1/-1/2 and u mult by the reciprical to get -2

Answer 5

or 2sqrt(3)/(3) if you rationalize denominator

Answer 6

@ozzman77

sin (2pi/3) = sqrt(3)/2...not 1/2 or -1/2

2pi/3 is a second quadrant angle where sin and csc are positive

Answer 7

opps I looked at the cos...either way the explenation is the same jst use the sqrt(3)/2
srry bout that and @Easyaspi314 thanks for catching that

Answer 8

n/p
