Finding Exact Value of Y

[tristatefabricatorsinc]

Find the exact value of y

y = (csc^-1)(-2)


I am confused how to do this.

 

[pka]

Which of the functions is asc<SUP>−1</SUP>?
Pease spell it out.
Is it the arcsecant?

I got it now, I have to use radian mode on my calc and enter it as

csc^-1(-2) as it is

and get... -.523599

Thanks
