Area between curves in polar coordinates. Let Dbe a region in xy-plane which can be represented and r 1( ) r r 2( ) in polar coordinates. Using the formula for the area volume and surface area word problems pdf i.e. we can use a double integral to compute the area of a plane region. With this in mind Calculate the Area of the region inside the circle r = 2 and to the right of the line x = 1. Here we can Compute the Area in the firs quadrant and double the result.

- Now we turn our attention to deriving a formula for the area of a region bounded by a polar curve. Recall that the proof of the Fundamental Theorem of Calculus used the concept of a Riemann sum to approximate the area under a curve by using rectangles. For polar curves we use the Riemann sum again, but the rectangles are replaced by sectors of a circle.
