Question 797485
assume that a is an angle in standard position whose terminal side contains the point (-2, 2 square root of 3) find the exact values of the functions
**
Reference angle is in quadrant II where cos<0 and sin>0
Hypotenuse of reference right triangle=&#8730;((-2)^2+(2&#8730;3)^2)=&#8730;(4+12)=&#8730;16=4
sin(a)=2&#8730;3/4=&#8730;3/2
cos(a)=-2/4=-1/2
tan(a)=sin/cos=(&#8730;3/2)/(-1/2)=-&#8730;3
csc(a)=2/&#8730;3=2&#8730;3/3
sec(a)=-2
cot(a)=-1/&#8730;3=-&#8730;3/3
