Answer:

When

θ

=

0

,

π

2

,

π

,

π

2

,

2

π

, we have

r

=

1

and when

θ

=

π

4

,

3

π

4

,

5

π

4

,

7

π

4

, we have

r

=

0

Hence, the courve moves from

r

=

1

at

θ

=

0

to

r

=

0

at

θ

=

π

4

to

r

=

1

at

θ

=

π

2

. Note that in between at

θ

=

π

6

we have

r

=

1
