We will also discuss finding the area between two polar curves > to get the area between the polar curve r = f (θ) and the polar curve r = g (θ), we just subtract the area inside the inner curve from the area inside the outer curve it is clear from the figure that the area we want is the area under f minus the area under g, which is to say ∫ 1 2 f (x) d x − ∫ 1 2 g (x) d x = ∫ 1 2 f. Here we derive a formula for the arc length of a curve defined in polar coordinates. The area inside a polar curve is given by a formula for a, where [alpha,beta] is the interval over which we’re integrating, and where r is the equation of the polar curve.
