Provide an appropriate response.Graph y = sin-1(sin x). Explain why the graph looks like it does.
What will be an ideal response?
When plugging in angles such that - 
? x ? 
the output is the same angle. However, the range of 
Therefore, when plugging in angles outside of that interval the output will be different. Instead of getting back the same angle you are getting back the first or fourth quadrant angle whose sine is the same value. The overall result is a function going back and forth between 1 and -1 in a linear fashion.
