Isn't it a function considered a function if it has no intersecting lines? Maybe you should graph it and see if it has intersecting lines or not. If it doesn't the it's a function if
it does then it's not. I think..?

Find all theta in the interval [0, 2pi) that satisfy the equation.

Murljashka [212]

$2\cos\theta*\tan\theta + \tan\theta = 0
\\
\\2\cos\theta* \frac{\sin\theta}{\cos\theta} + \frac{\sin\theta}{\cos\theta} = 0
\\
\\ 2\sin\theta + \frac{\sin\theta}{\cos\theta} = 0
\\
\\ \frac{2\sin{\theta}\cos{\theta}}{\cos{\theta}} + \frac{\sin\theta}{\cos\theta} = 0
\\
\\ \frac{2\sin{\theta}\cos{\theta}+\sin{\theta}}{\cos{\theta}} =0
\\
\\ 2\sin{\theta}\cos{\theta}+\sin{\theta}=0
\\
\\ \sin\theta(2\cos\theta+1)=0
\\
\\ \sin\theta=0 \Rightarrow \theta=0, \pi,2\pi
\\
\\2\cos\theta=-1
\\
\\\cos\theta=- \frac{1}{2} \Rightarrow \theta= \frac{2\pi}{3} , \frac{4\pi}{3}
$

Therefore, $\theta=0, \pi,2\pi ,\frac{2\pi}{3} , \frac{4\pi}{3}$
