Question

express the exact value of of csc 60 degrees with a rational denominator. please show all work.

Answer 1

csc 60 = 1 / sin 60 = 1 / (sqrt3/2) = 2 / sqrt3

Answer 2

can you continue from here - rationalize the denominator

Answer 3

multiply top and bottom by sqrt3

Answer 4

im getting confused csc 60= 1 how? also how comes u must use sin and square root can u explain it a bit more please.

Answer 5

no its a trig identity csc x = 1/sin x

Answer 6

sin 60 = sqrt3 / 2
so csc 60 = 1 / (sqrt3/2) = 2 / sqrt3

Answer 7

rationalizing the denominator
2 / sqrt3 * sqrt3 / sqrt3 = 2sqrt3 / 3

Answer 8

okay i understood the sin 60 part. can u help me with the rationalizing denominator again. what did u do with the 2?
