Question

Please Help!

Find the exact value: csec 22pi/3

Answer 1

22pi/3 = (21pi + pi)/3 = 7pi + pi/3

Answer 2

ok so for this question we know csc = 1/sin alright. and we also know that 22pi/3 is 1320.

So one whole circle is 360 degrees and if we keep going around to 3 circles we end up at 1080. which is still 0 if you think about it then from there do 1320 - 1080 = 240 so basically now your finding your exact value of 240.

and if you do that you get sin 240 = -sqrt(3)/2 and this implies csc 240 = -2/sqrt(3) :)

Answer 3

it's in third quadrant.
