How do you graph y=2cot(x+pi/2) and include two full periods?

Feb 22, 2018

Plot x == (0, $\frac{\pi}{2}$, $\pi$, $3 \frac{\pi}{2}$, $2 \pi$, $5 \frac{\pi}{2}$, $3 \pi$, $7 \frac{\pi}{2}$, $4 \pi$)
$2 \pi = 1 p e r i o d$
$4 \pi = 2 p e r i o d$
You can plot any value in for x but plot $4 \pi$ of x!
