Numeric vs Fitted vs Resampled Derivative Comparison Chart #1465930 (License: Personal Use)

The plot displays three derivative estimation techniques: blue for numeric derivative (finite differences), green for fitted derivative (model-based smoothing), and red for resampled derivative (interpolation + differentiation). All curves start at -5.0 and converge near -0.5 as x approaches 1.0, with notable divergence between x=0.2 and x=0.6, revealing trade-offs in noise robustness and fidelity.

Used in technical documentation, academic papers, or data science tutorials to illustrate derivative approximation strategies; supports user intent around understanding numerical stability, smoothing effects, and resampling impact in signal or function analysis.
