WebFit Polynomial to Trigonometric Function. Generate 10 points equally spaced along a sine curve in the interval [0,4*pi]. x = linspace (0,4*pi,10); y = sin (x); Use polyfit to fit a 7th-degree polynomial to the points. p = polyfit (x,y,7); Evaluate the polynomial on … WebAug 2, 2024 · Where engineers and technicians can get into trouble is by changing the equation order. If a line does not fit well, it may be tempting to try to model it with a parabola, cubic, or another polynomial instead. If they do this, they will get an R^2 value of 1, as they will have found a polynomial that snakes through every data point.
