Problem 52 Hard Difficulty

Investigate the family of curves defined by the parametric equations $ x = \cos t $, $ y = \sin t - \sin ct $, where $ c > 0 $. Start by letting $ c $ be a positive integer and see what happens to the shape as $ c $ increases. Then explode some of the possibilities that occur when $ c $ is a fraction.

the problem is investigated. The family off curves did find the bus. Parametric equations actually put this society while going to sign the minus sign stayed home steam wire seasick with his and cereal. Start by light and save your positive integer on DH. Say what happens to the ship at sea increases. They explored some of the possibilities that our care What C is a fraction. Look at this graph. Here I see a single one. The curve is a line segment. I say you got to. It's a curve into a sex itself. At one point, my C is equal to three. Curve intersects itself at two points. Must see is it four? The curve intersects itself at three points so we can guess. For safe go to some in and this positive interview the curve intersects the south at a month. One points. Then let's look at some examples. What sees a fraction. If the denominator is equal to three we have. That's a look at this example. If sees it, criticism. One on the denominator is equal to three. Your half the curve dissects itself at fifteen points. It says he got a four one three Andi. If sees you go too far over three, the curve in the sects itself. All right, eighteen points and over half. But if the denominator is not equal to three point damn point if this is too, we have if this is seven over too, the curve in just sects in the south at their team points.
