Radius of Curvature finding tool using Auto Level

Important Note:- This calculator is intended for preliminary estimation and educational purposes only. The results generated here are based on standard simplified assumptions and may not consider all factors necessary for a comprehensive Radius of Curvature calculations.

Higher-degree polynomials (like degree 9 or 10) can pass through every data point exactly, but they often:

Wobble wildly between points,

Predict poorly outside the range,

Give meaningless curvature.

So, only go to higher degrees if lower ones (e.g., 2–6) don’t give a good R².

To fit a degree-d polynomial, you need at least d + 1 points.

Example:

To fit a quadratic (degree 2), you need ≥ 3 points.

To fit a 6th-degree curve, you need ≥ 7 points.

Also, having only just enough points can lead to unstable or poor generalization. So:

For robust fitting: use more than d + 1 points.
