To write $r(t) = a \cos(wt) + b \sin(wt)$ in polar coordinates, we can use the identity $\cos(\theta) = \frac{x}{r}$ and $\sin(\theta) = \frac{y}{r}$, where $r$ is the distance from the origin to the point $(x, y)$ and $\theta$ is the angle between the positive x-axis and the line connecting the origin to the point. Then, we can express $r(t)$ in polar coordinates as $r(t) = \sqrt{a^2 + b^2} \cos(wt - \phi)$, where $\phi = \arctan\left(\frac{b}{a}\right)$ is the angle between the positive x-axis and the line connecting the origin to the point $(a, b)$. **
