Understanding the concept of areas in the polar coordinate system is a fundamental part of advanced mathematics. Wolfram, a prominent figure in the computational world, offers a comprehensive tool for this purpose – an Area Between Two Polar Curves Calculator. This article will delve into the working of this calculator, explaining the formula it uses, and offering a demonstrative example.

Understanding Polar Coordinates

Before we jump into the calculator, it’s important to understand what polar coordinates are. Polar coordinates offer an alternative way of representing points in a plane. Instead of using x and y coordinates like the Cartesian coordinate system, polar coordinates use the distance of the point from the origin (r) and the angle formed by the point with respect to a reference direction (θ).

The Formula Behind the Calculator

The area between two polar curves is found by integrating the difference of the squared functions representing the curves, with respect to the angle, over the given interval.

The formula is as follows:

A = 1/2 ∫ from α to β [(f(θ))^2 – (g(θ))^2] dθ

Here, f(θ) and g(θ) are the functions representing the two polar curves, and α and β are the limits of the region where the area is calculated. The integral measures the difference of areas swept by the radius as θ varies within the interval [α, β].

An Example

Let’s say we have two polar curves, r1(θ) = θ and r2(θ) = 2θ, with the angle θ varying from 0 to π. Using the formula above, we find the area A between the two curves from θ = 0 to θ = π as follows:
