This tool calculates the length of a polar curve for you efficiently and accurately.
How to Use the Length of Polar Curve Calculator
Enter the polar equation (r as a function of θ) in the given field. Specify the start and end angles (θ₁ and θ₂) in radians, and the number of segments for numerical integration. Click “Calculate” to compute the length of the polar curve.
Explanation of the Calculation
The length of a polar curve given by r(θ) from θ₁ to θ₂ is calculated using the integral formula:
L = ∫[θ₁ to θ₂] √((dr/dθ)² + r²) dθ
This calculator uses numerical integration (trapezoidal rule) to approximate the length. The number of segments controls the accuracy of the approximation.
Limitations
The accuracy of the result is dependent on the number of segments used for numerical integration. More segments provide higher accuracy but at the cost of increased computation time. Ensure the function r(θ) can be evaluated for the given range of θ.
