### Spiral

A spiral is formed with a simple equation $r=a\theta, a\neq 0$. The graph below set 'a' as positive, therefore there are two equations for you to tick. Choose whichever equation you prefer, you may choose both as well, then drag the value of 'a' according to your preference. Then, drag the value of $\theta$ to view the forming of spiral.
