1. gjhfdfg

csc -( pi / 6 )

2. Zelda

Well, here we go: You started with: $\csc (-\frac{ \pi }{ 6 })$ Is that right?

3. gjhfdfg

Yes

4. Zelda

Now, what is equal to csc (x)? (In terms of another trig function)

5. gjhfdfg

1/sin?

6. Zelda

Okay good, now we get this: $\csc (-\frac{ \pi }{ 6 }) = \frac{ 1 }{ \sin(-\frac{ \pi }{ 6 }) }$ Correct?

7. gjhfdfg

Yes,

8. Zelda

So what do you get for: $\sin (-\frac{ \pi }{ 6 })$

9. gjhfdfg

-.5

10. Zelda

Great, now what is 1/(-1/2)?

11. gjhfdfg

-2

12. Zelda
