Question statement

You are shown four different curves below. For each of them, select the correct formula for the radius $r$ .

The phase $\theta$ is always in the interval $[0,2\pi)$ . Use the slider in the upper right of the canvas to display more of the curve, and to see how $r$ depends on $\theta$ .

(Hint: Some of the given expressions are quite complicated -- it is not necessary to understand them completely. Try to think of ways to eliminate the wrong formulas.)

Give any introductory information the student needs.
