How do you graph two cycles of y=-2.25tantheta?

Nov 7, 2017

See below

Explanation:

$y = - 2.25 \tan \theta$

$y$ has the standard graph of $\tan \theta$ scaled by $- 2.25$

To graph two cycles note that $\tan \theta = 0$ at $0 \mathmr{and} \pi$ and is undefined at $\frac{\pi}{2}$.

As graph of $y$ below.
