 FIND THE EXACT VALUES WHEN ANGLE = 11pi/6 . DRAW ANGLE ON A UNIT CIRCLE?

---

(11/6)pi is the same as -(1/6)pi or -30 degrees

---

If you draw it on the unit circle,

the radius is "1"

the y value is "-1/2"

the x value is "(1/2)sqrt(3)"

-------------------------------------

sin = -1/2

cos = sqrt(3)/2

tan = -sin/con = -1/sqrt(2)

-----

csc = -2

sec = 2/sqrt(2)

ctn = -sqrt(2)

========================

Cheers,

Stan H.
