This time we are graphing *r* = 0.2 *θ* in polar coordinates.

**Drag** the blue dot (slowly) left and right to change the angle *θ* and observe the resulting changes in the value of *r*.

**Hint:** Let go of the blue dot to see a smooth curve at any time. You can trace out positive or negative angles.

Note the value of *r* is always `0.2` times the value of *θ* (of course, we are in **radians**).

Here's an image in case you can't see the graph above.
