What is the range of y = sin θ ? [–1, 1] [0, ∞) all real numbers 2π

Range of the given function is:

                              [-1,1]

We know that the graph of a sine function i.e.

is a continuous curve that repeats itself after a fixed interval of 2π i.e. fundamental period of function is: 2π.

Also, the minimum value of the function is: -1

and the maximum value of the function is 1

and all the other value lie between these.

Hence, the range of y=sinθ is: [-1,1]
