Question
$f(x)= \begin{cases}1, & \pi / 2<|x|<\pi \\ 0, & \text { otherwise }\end{cases}$
Step 1
It is defined as 1 for $\pi / 2<|x|<\pi$ and 0 otherwise. This means that the function is equal to 1 for values of $x$ that are between $\pi / 2$ and $\pi$ in absolute value, and 0 for all other values of $x$. Show more…
