Answer:
The range is [tex]-1<y<1[/tex]
Step-by-step explanation:
The simple trigonometric functions [tex]sinx[/tex] and [tex]cosx[/tex] have the standard range [tex](-1;1)[/tex]. This means that these functions cannot give -1 or 1 as a result, because this values in their range is undetermined. So, basically, these functions only can give results between this two number. You can better see this with the graph attached, there you can notice the limitation of the given function.
