Question 671121: By using sum or difference formulas, sin(x−pi) can be written as:?
A. -sin (x)
B. sin (x)
C. -cos (x)
D. cos (x)
E. All the above
F. None of the above
My ans: I got -sin (x) and -cos (x) for sure. Not sure if this is correct. I have a feeling it's All of the above, but my notes do not say otherwise. Thank you! Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! By using sum or difference formulas, sin(x−pi) can be written as:?
**
sin(x-π)
=sinxcosπ-cosxsinπ
=sinx*-1-cosx*0
=-sinx-0
=-sinx
