When **n** = 1, the graph does not resemble
a flower, but it still is an "**n** leaf rose" except
that since **n** =1, there is only 1 petal. The graph of this
special case is called a cartioid.

The variables **a** and **b** will have
the same impact on the graph that they do in the ordinary "**n**
leaf rose."

For example, in this graph we can see that
a larger value of **b** produses a second set of petals, and
that the larger the value of **b**, the larger the petals are.

And in this graph, we can see the effects of
**a** on the graph. A larger value of **a** results in a
larger outer petal and a smaller inner petal than a smaller value
of **a** does.

It is interesting to see that by keeping **b**
= 1, **n**=1, that larger values of **a** will round out
the graph of the cartioid.

Even larger values of **a** result in graphs
that approach a circle.

Notice, here, when **a** = 100, that the
graph is ALMOST a circle with a radius of 100.
