cos 5π/6

Find the sine, cosine, and tangent for the following point on the unit circle. 

(Hint: What is the relationship between coordinates on the unit circle and sine, cosine, and tangent?)

$$\left(\frac{2}{9},\ \frac{\sqrt{77}}{9}\right)$$  

Based on the unit circle, what is the value of sin?

Match the trig function with it value on the unit circle:

What value on the unit circle represents sine?

Using the unit circle x-values correspond to ​ (a)   , y-values correspond to ​ (b)   , and y-values divided by x-values correspond to ​ (c)
