It is the arc length s. r * θ = s this comes from the definition of radiance (rad) the angle unit. What you found was the arc length or circumference of the circle. To become the area take the integral ∫ ds dr. Because for a small arc length ds times a small distance dr you become a rectangle..

polarplot(theta,rho) plots a line in polar coordinates, with theta indicating the angle in radians and rho indicating the radius value for each point.The inputs must be vectors of equal length or matrices of equal size. If the inputs are matrices, then polarplot plots columns of rho versus columns of theta.

We use polar coordinates as an alternative way to describe points in the plane. In polar coordinates, we describe points via their angle (called argument or polar angle) with the positive x-axis measured in counterclockwise direction, and the distance from the origin (called radial distance). See figure below.

• θ = 2 π / 3 → r = − 2. θ = 5 π / 6 → r = − 3 − 1. θ = π → r = − 3. If r = 0, then cos. ⁡. ( θ) = 1 / 2 and so θ = π / 3 provided 0 ≤ θ < π. This means that the point ( 0, π / 3) is on the graph, and an equation of the tangent line there is θ = π / 3. It is called limacon. Share.
• To convert back and forth between polar and rectangular coordinates, we have the following formulas: \begin {aligned} x &= r \cos \theta \\ y &= r \sin \theta\\ r^2 &= x^2 + y^2 \\ \tan \theta^* &= \dfrac {y} {x}. \end {aligned} x y r2 tanθ∗ = rcosθ = rsinθ = x2 +y2 = xy . ^* ∗ One must consider what quadrant the point is in when computing

• As noted above we can get the correct angle by adding p p onto this. Therefore, the actual angle is, θ = π 4 + π = 5 π 4 θ = π 4 + π = 5 π 4. So, in polar coordinates the point is ( √ 2, 5 π 4) ( 2, 5 π 4). Note as well that we could have used the first θ θ that we got by using a negative r r.
