Question

What is the range of y = sin θ ?

Answer 1

please note that, by definition of the function:
\[f(\theta)=\sin \theta\]
we have the subsequent natural limits:
\[-1\le y=f(\theta)\le +1\]
\[\forall \theta \in \mathbb{R} \]

Answer 2

im really confused now..

Answer 3

why? please?

Answer 4

if you graph sin x you can see the range is between -1 and 1

Answer 5

@joslynraay please think about the unit circle
