You can simply evaluate this problem on a calculator by taking the sin of 120� and finding its reciprocal, but I'm sure this is not what your teacher wanted you to do.
..
First you must find 120� on the unit circle, then determine the reference angle from which you would evaluate the given trig function.
Starting from zero on the unit circle, rotate 120� counter-clockwise.
Notice that the terminal side makes a 60� angle with the x-axis.
This is the reference angle in quadrant II.
By now, you should have memorized that csc 60�=1/sin 60�=2/√3.
csc and sin functions are<0 in quadrant II
so the final answer:
csc(120�)=-2/√3 or-2√3/3
There is more to it than this, but I hope this helps
