About the Comparison

This tool compares two methods of interpolation:

  • Linear Interpolation: A straight line between known data points.
  • Polynomial Curve: A curve based on the formula: result = input * factor^2 + factor^3 + factor^4, where factor is the input normalized to a 0-1 range.

The graph shows both methods, with the linear interpolation adapting to your input data points (blue dots) and the polynomial curve providing a smooth, non-linear alternative. This comparison can be useful for understanding different approaches to estimating values between known data points and for visualizing how different mathematical models can produce varying results.
