Question

find all values of x in the interval [-2pi, 2pi] that satisfy's the following equation: sin (x) = -1

Answer 1

When I put y=sin(x) in my calculator, the function only displays 3 locations. I am unsure of whether to change my WINDOW in my calculator to -2pi and 2pi for both the X and Y axis.

Answer 2

3pi over 2 or 270 degrees is definitely one of the locations

Answer 3

I think it may just be -1.
