Work Step by Step

We can plot the point by moving to angle $\theta=\frac{\pi}{2}$ counterclockwise, and then to $r=3.5$ as shown in the figure. a. We can find another representation for the same point using the given range as $(3.5,\frac{5\pi}{2})$ b. We can find another representation for the same point using the given range as $(-3.5,\frac{3\pi}{2})$ c. We can find another representation for the same point using the given range as $(3.5,-\frac{3\pi}{2})$
