-sinx-sqrt(2)

[Travis_salyer]

I'm working on a calculus problem and my trig has disappeared from my head.
I can't seem to figure this out.
I'm trying to figure out the zeros of this but I can't
I set it to zero so I got this far:
sinx=-sqrt(2)
but now I'm stumped

any help would be great

Are there any zero crossings?

I'm trying to figure out the zeros of this

sinx=-sqrt(2)

Two questions to ask yourself.

What is the value of -\(\displaystyle \sqrt{2}\)?

Is that value in the range of the sine function?

:cool:

To easily answer Quaid's question try using your calculator to evaluate arcsin(-Sqrt(2)) as is a solution to sin(x) = -Sqrt(2), (but not the general solution).

RIGHT M. Denis (post below), assuming Travis is working in the complex domain (Wolfram solution - must think about that myself).
