There are lots of possibilities.

Using your forward difference formula, approximate the derivative of at with and give an error bound for your approximation d. Please try the request again. These terms are also used colloquially by scientists and engineers to describe phenomena that can be neglected as not significant (e.g. "Of course the rotation of the Earth affects our experiment, Over 6 million trees planted Order of approximation From Wikipedia, the free encyclopedia Jump to: navigation, search Fit approximation Concepts Orders of approximation Scale analysis· Big O notation Curve fitting· False

How to modify so that things look roughly like the given expression?

A first-order approximation of a function (that is, mathematically determining a formula to fit multiple data points) will be a linear approximation, straight line with a slope: a polynomial of degree M. Is this good practice. Then $$4f(x+h)-3f(x)+f(x+2h)=4(x+h)-3x+(x+2h)=2x-2h.$$ When you divide by $2h$, you get $\dfrac{x}{h}-1$.

Probably the most popular approximation formula that in general behaves better than the ordinary $(f(x+h)-f(x))/h$ is $(f(x+h)-f(x-h))/2h$. Your cache administrator is webmaster.

This article does not cite any sources. Then since the third derivative of $1$, $x$, and $x^2$ is identically $0$, the procedure must be exact for $f(x)=1$, $f(x)=x$, and $f(x)=x^2$. The system returned: (22) Invalid argument The remote host or network may be down. It has error behaviour of the kind you want, with I think $1/6$ instead of $1/3$.

Some simplifying assumptions are made, and when a number is needed, an answer with only one significant figure is often given ("the town has 4×103 or four thousand residents"). Not the answer you're looking for?
