Chapter 9: Q. 30 (page 567)

In Problems 17–30, plot each point given in polar coordinates.
$(- 3, - \frac{π}{2})$

Short Answer

Expert verified

The given point in polar coordinate is

Step by step solution

01

Step 1. Given Information

The given point is $(- 3, - \frac{π}{2}) .$

The point $(r, θ)$ is the distance from the origin and angle on the unit circle in the polar coordinates.

02

Step 2. Plotting the point

Now, to plot the points we have $r = - 3, θ = - \frac{π}{2}$

Since r is negative the ray will be in the opposite direction of $- \frac{π}{2} .$
