Chapter 9: Q. 9 (page 567)

Match each point in polar coordinates with either A,B,C or D on the graph.

(2,-11蟺6)

Short Answer

Expert verified

Point (2,-11蟺6)is a correct match with A on the graph.

Step by step solution

01

Step 1. Given information

We have been given a point in polar coordinates (2,-11蟺6).

We have to match this point on the graph.

02

Step 2. Plot the given point on the polar coordinate as per the value of r and θ

To graph a point in polar coordinates (r,胃), we have to know that r is the distance between the point and the origin and is the angle with respect to the polar axis, now when the value of r is negative the point is located in the opposite sense of the angle, and if 胃is negative this means that the angle is taken on the clockwise sense.

Therefore, the correct match is A.
