Question 920151
Find the exact value of each of the remaining trigonometric functions of θ.
cos &#952;=-1/3 , sin &#952; < 0
sin &#952; = -&#8730;8/3
tan &#952; = &#8730;8
csc &#952; = -3/&#8730;8=-3&#8730;8/8
sec &#952; = -3
cot &#952; = 1/&#8730;8=&#8730;8/8
***
Reference angle in quadrant III in which cos<0, sin<0
Identity: sin^2&#952;+cos2&#952;=1
sin&#952;=-&#8730;(1-cos^2&#952;)=-&#8730;(1-1/9)=-&#8730;(8/9)=-&#8730;8/3
