SOLUTION
Step 1 :
In this question, we are meant to find the range of y = sin x .
Step 2:
From the graph, we can see clearly that:
The graph of y=sin(x) is like a wave that forever oscillates between -1 and 1, in a shape that repeats itself every 2π units.
Specifically, this means that the domain of sin(x) is all real numbers, and the range is [-1,1].
CONCLUSION:
The range of y = sin x is
