Gregory Newton Formula FAQs
What is Gregory Newton’s Forward Difference Formula?
Gregory Newton’s forward difference formula is a way used to find value of any function at points where its value is not given but its value at other points is given.
When to use Gregory-Newton Forward Formula, and when Backward Formula?
Gregory-Newton Forward Formula is used when your data points are arranged in ascending order (left to right). Gregory-Newton Backward Formula is used when your data points go in descending order (right to left).
What is Common Difference (h) in Gregory-Newton Formula?
Common difference (h) is the difference between consecutive x-values. It’s essential for calculating differences like Δy, its square and higher powers.
Can Gregory-Newton Formula is Used for Non-Equidistant Data Points?
No, Gregory-Newton Formula is designed for evenly spaced data points. If your data points aren’t equally spaced, it is not used.
Gregory Newton Interpolation Formula
Newton-Gregory Forward Interpolation Formula is an interpolation method when our data points are evenly spaced. Interpolation is a method in maths used to make educated guesses about values between two points we already know. We can say that the Gregory–Newton forward difference formula involves finite differences that give an approximate value for f(x), where x = x0 + θ.h, and 0 < θ <1. Approximation of f(x) ≈ f0 + θ.Δf0 gives the result of Linear Interpolation.
