You can put this solution on YOUR website! Given point p at (-(sqrt11)/6, 5/6), find sin, cos, and tan. Is this on the unit circle?
***
Given reference angle is in quadrant II where sin>0, cos<0 and tan<0
hypotenuse=√(√11/6)^2+(5/6)^2)=√(11/36)+25/36)=√(36/36)=1
Given point is on the unit circle
sin=5/6
cos=-√11/6
tan=-5/√11
