r=sin(2*theta), finding the area of one of the petals of this four petal roses ## Example: Areas in Polar Coordinates

In this video, I work through an example of finding the area of a region in polar coordinates. ## Area Bounded by Two Polar Curves – Part 1

This video explains how to determine the area between two polar curves. http://mathispower4u.yolasite.com/ ## Area between two polar curves

To find the area between two polar curves, just take the area inside one minus the area inside the other. We illustrate by finding the area between a cardioid and a circle. ## Surface Area of Revolution of Polar Curves

This calculus 2 video tutorial explains how to find the surface area of revolution of polar curves. It explains how to find the surface area of by rotating the curve about the polar axis and about the line theta equals pi/2. This video explains how to calculate the surface area of a sphere using calculus… ## Calculus 2: Polar Coordinates (38 of 38) Area Between 2 Curves=?

Visit http://ilectureonline.com for more math and science lectures! In this video I will find the area between 2 polar curves r1=3cos(theta), circle, and r2=1+cos(theta), cardioid. I will need to find the points of intersection by setting r1=r2. First video in the series can be seen at: https://youtu.be/qa7UE9IOJuA ## Polar Coordinates: Area: Example 2: Cardioid and Circle

In this video I go over another example on calculating the area of polar curves and this time find the area enclosed by a circle yet separated by a cardioid. The Cardioid, or Heart in Greek, is the same formula I had previously graphed in my earlier example video. To save time, I plot both… ## AREA BETWEEN TWO POLAR CURVES
