An Introduction to Polar Coordinates (8.7.1)

Question 1

• Instead of describing points using Cartesian or rectangular coordinates, you can use polar coordinates to describe points based on their distance from the origin and their angle from the polar axis.

Answer 1

• Instead of describing points using Cartesian or rectangular coordinates, you can use polar coordinates to describe points based on their distance from the origin and their angle from the polar axis.

Question 2

• In polar coordinates, a point is specified by an ordered pair (r, θ), where r is the distance of the point from the origin and θ is the angle of the point from the polar axis. The polar axis is located in the same place as the positive x-axis of a rectangular coordinate system.

Answer 2

• In polar coordinates, a point is specified by an ordered pair (r, θ), where r is the distance of the point from the origin and θ is the angle of the point from the polar axis. The polar axis is located in the same place as the positive x-axis of a rectangular coordinate system.
