1. ## Circular function value

Find the exact circular function value:

csc(-11pi/6)

2. ## Re: Circular function value

cosecant is the reciprocal of sine

find $\sin\left(-\dfrac{11\pi}{6}\right)$ and determine the cosecant

you do know your unit circle, correct?

3. ## Re: Circular function value

I'm still learning it, but I have it in hand. Either I'm looking at it wrong or there are no negatives listed

4. ## Re: Circular function value

what do you know about co-terminal angles ... ?

5. ## Re: Circular function value

The first thing I would notice is that -11/6= -1- 5/6= -1- 1/2- 1/3= -3/2- 1/3. So to go around the unit circle $-\frac{11}{6}\pi$ counter clock wise $(-3/2)\pi$. to the point (-1, 0). The point we want is another $\frac{1}{3}\pi$ up so $\pi/2- \pi/3= \pi/6$ radians or 30 degrees down from the 0 point.
