WebNov 16, 2024 · r = √x2 +y2 r = x 2 + y 2 Note that technically we should have a plus or minus in front of the root since we know that r r can be either positive or negative. We will run with the convention of positive r r here. Getting an equation for θ θ is almost as simple. We’ll start with, y x = rsinθ rcosθ =tanθ y x = r sin θ r cos θ = tan θ Webr * 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. Some all rectangles up and you get the area of it.
