How can I find a polynomial that fits a given table? [closed]
The first difference is 1, 4, 7, 10, 13, 16 The second difference is 3, 3, 3, 3, 3, 3 Since the second difference is constant this would be quadratic and I would have $\frac {3} {2}n^ {2}$ So now I will take …
Numerical Method Forward Finite Difference Coefficient
Sep 16, 2019 · Could someone please give me a method of deriving part of this table? This is used in numerical methods, the forward finite difference method. I've spent a few days working on this, but, …
What are the Differences Between a Matrix and a Tensor?
Jun 5, 2013 · What is the difference between a matrix and a tensor? Or, what makes a tensor, a tensor? I know that a matrix is a table of values, right? But, a tensor?
numerical methods - Problem in Understanding an Illustrative Example ...
Aug 12, 2023 · The original table of function values is presumably from a smooth function at equidistant steps at a small step size. Thus in the section under observation it can be assumed to be polynomial …
Can someone explain in general what a central difference formula is …
Aug 5, 2014 · This is the central difference formula -- it gives an approximation for the value of the derivative at a point midway between ("central" to) each contiguous pair of points in the data.
How to use central difference formula if step size is not constant
Jan 30, 2021 · As that is obviously not possible, use the Taylor expansions to find a correct approximation formula. You could also just take the mean value of the first two as approximation of …
What is the difference between only if and iff?
As far as the difference goes, (which I guess was the specific question), if and only if means just that. $p$ if and only if $q$ means ($p$ if $q$) AND ($p$ only if $q$).
numerical methods - Error estimator for forward finite difference ...
1 I'm studying numerical analysis and for the approximation of a derivative around a given point we have for the forward finite difference: $$ (\delta_+f) (\bar x) = \frac {f (\bar x + h) - f (\bar x)} {h}$$ Now to …
Statistic about Actual vs. Projected - Mathematics Stack Exchange
How do I calculate this? I forgot if this statistic is called Percent Difference or something else, I remember learning it in Chemistry for actual vs. experimental. Stats: Actual Value: 16 Projected …
Difference between Backward and Forward differences
In numerical methods we are all familiar with finite difference table where one can identify backward and forward difference within same table e.g. given any entry in finite difference table, one can identify it …
