Question
State whether the function $y=\sin x$ is increasing or decreasing on the given interval. (The terms increasing and decreasing are explained on page $159 .$ )$$-\pi / 2<x<\pi / 2$$
Step 1
The interval is $-\pi / 2<x<\pi / 2$. This means we are looking at the values of $x$ between $-\pi / 2$ and $\pi / 2$. Show more…
