Graphical representation of Interpolation and Extrapolation
In this post we define some definitions of numerical analysis and their formulas which are very important related to the topic.There are seven types of it.
The process of finding the value of function inside the given range of arguments is known as interpolation
The process of finding the value of function outside the given range of arguments is known as interpolation.
There are following Interpolation Formulae that are used in interpolation.
- Geogory-Newton forward Interpolation Formula
- Geogory-Newton backward Interpolation Formula
- Gauss Forward Interpolation Formula
- Gauss Backward Interpolation Formula
- Stirling Formula
- Bessel’s Formula
- Laplace-Everett’s Formula
1. Geogory-Newton forward Interpolation Formula
The formula of the form given below is called Geogory-Newton forward Interpolation Formula.
2. Geogory-Newton Backward Interpolation Formula
Geogory-Newton Backward Interpolation Formula is given as
3.Gauss Forward Interpolation Formula
Gauss Forward Interpolation Formula given as
is called Gauss Forward Interpolation Formula
4. Gauss Backward Interpolation Formula
The formula of the form given below is called Gauss Backward Interpolation Formula.
The formula given below is called Stirling Formula if
The formula of the form given below is called Bessel’s Formula
The formula of the form given below is called Laplace-Everett’s Formula
You can also attempt mcqs about numerical analysis test 01 and so on.
pakmath team will provide these results in the next posts and also with their proofs. But these proofs will be provided in the separated posts.
Oh my goodness! an amazing article dude. Thanks However I’m experiencing situation with ur rss . Don’t know why Unable to subscribe to it. Is there anybody getting equivalent rss drawback? Anybody who is aware of kindly respond. Thnkx
