## anonymous 4 years ago Evaluate without using a calculator: tan (330) My answer was (-sqrt 3)/3 Please check my answer...i'm awful at math :/ Thanks! :)

1. anonymous

This is correct! :)

2. anonymous

Thanks! Um, but i don't understand my next problem which is csc (-405) Can you explain to me please?

3. anonymous

I'm not too familiar with csc, but what I will tell you is that -405degrees is the same as -45 degrees, if that is hepful!

4. anonymous

csc (angle) = 1/ sin (angle) cosecant is just the reciprocal of the sine function.

5. anonymous

would the answer be $\sqrt{-2}$?

6. anonymous

sorry i meant -$\sqrt{2}$

7. anonymous

forgot the negative....

8. anonymous

she did do the negative, it was just in the next line. she did the negative out of equation editor and the sqrt(2) in the equation editor which moves it down to the next line it's a little ambiguous, but it is there.

9. anonymous

... so it's right? negative square root two? lol xD

10. anonymous

yes... see? don't every say you're awful at math again!!! good work. :)
