The general equation of roses with $\"\"$ petals is $\"\"$ or $\"\"$ , where $\"\"$ .

If $\"\"$ is odd, then the rose has $\"\"$ petals.

If $\"\"$ is even, then the rose has $\"\"$ petals.

Graph the rose with $\"\"$ petals.

Let $\"\"$ and $\"\"$ can be any value, so set $\"\"$ . Then draw the petals $\"\"$ units from the center.

Use sine or cosine, If we use cosine, then a peak of one of the petals where be at $\"\"$ .

$\"\"$ .

The equation is $\"\"$ .

Graph the equation $\"\"$ :
