WebJun 9, 2024 · 2 Answers. The trick is that instead of using t as a parameter along one axis, you use it as a free parameter, with t = 0 at the beginning of the curve, and t = 1 at the end of the curve, with 0 ≤ t ≤ 1 specifying the points on the curve.

WebJul 18, 2024 · Cubic spline interpolation is a way of finding a curve that connects data points with a degree of three or less. Splines are polynomial that are smooth and continuous across a given plot and also continuous …
Web$\begingroup$ It looks like Wolfram Alpha proceeded with polynomial Interpolation. But what do you want? There are many interpolation techniques. For example some preserves monotonicity of the data, some not (like non linear polynomial interpolation). You need some details about the function you want to interpolate.
