Graph r=sin(2theta)

Using the formula ${\displaystyle r=a\sin \left(n\theta \right)}$ or ${\displaystyle r=a\cos \left(n\theta \right)}$, where ${\displaystyle a\ne 0}$ and ${\displaystyle n}$ is an integer ${\displaystyle >1}$, graph the rose. If the value of ${\displaystyle n}$ is odd, the rose will have ${\displaystyle n}$ petals. If the value of ${\displaystyle n}$ is even, the rose will have ${\displaystyle 2n}$ petals.
