I'm Sujoy and today I'll explain Everett's Interpolation Formula.

Topics Explained-
1. What is function of x or f(x)
2. Constructing Everett's Interpolation table
3. Everett's Interpolation formula
4. Finding del Y values
5. Finding value of y based on value of x
6. Doing Everett's Interpolation formula on Casio fx-991ES Scientific Calculator
7. Everett's Interpolation formula is similar to Newton's Forward and Newton's Backward Interpolation formulas, where difference between each term of x is equal, i.e Interval gap is same.
8. When difference between each term of x, or interval gap is not equal, we use Newton's Divided Difference formula, Lagrange's Interpolation Formula.
9. All the above mentioned formulas are used to find f(x) or y(x), i.e value of y depending on value of x. Also called function of x. But to find x(y), i.e value of x depending on value of y, also called function of y, Inverse Interpolation formula is used. I've videos on all the methods discussed, check my Numerical Methods Playlist, link given above.

That's it for now! How is the video? Let me know.
