You can estimate the second derivative in terms of the typical second finite differences in the data divided by the square of the interval widths. 7 Comments Show 4 older comments Algebra/Trig Review Common Math Errors Complex Number Primer How To Study Math Close the Menu Current Location : Calculus II (Notes) / Integration Techniques / Approximating Definite Integrals Calculus II [Notes] Links - Links to various sites that I've run across over the years. Hence, for an estimate of this error you need to obtain a good approximation to your data's second derivative within each of your trapezoid intervals.If your data is very accurate and

In this case notice that all the function evaluations at points with odd subscripts are multiplied by 4 and all the function evaluations at points with even subscripts (except for the Why is it a bad idea for management to have constant access to every employee's inbox?

If there's nothing stopping you from assuming your discrete samples came from this piece-wise linear function, then voila, you're done, and your area calculation was perfect!

That is, you know how to convert a pair of X and Y values into an estimate of the area for a single segment, and you can use error propagation http://en.wikipedia.org/wiki/Propagation_of_uncertainty Isn't that more expensive than an elevated system? I would love to be able to help everyone but the reality is that I just don't have the time. I really got tired of dealing with those kinds of people and that was one of the reasons (along with simply getting busier here at Lamar) that made me decide to

However in the second case the data has to be very accurate to achieve this with second differencing.The remedy when data is not sufficiently accurate is to widen the span of If you use the trapezoidal approximation, (f(a)+f(b))/2*(b-a), to approximate the integral of a quadratic function f(x) from a to b (which is what 'trapz' does,) it can be shown that the Log In to answer or comment on this question.

It is simply not correct to say that all measurements are so unreliable as to rule out any such estimate. The system returned: (22) Invalid argument The remote host or network may be down. Wenn du bei YouTube angemeldet bist, kannst du dieses Video zu einer Playlist hinzufÃ¼gen. So let $f(x)=x\cos x$.

In the mean time you can sometimes get the pages to show larger versions of the equations if you flip your phone into landscape mode. Those are intended for use by instructors to assign for homework problems if they want to. Wird geladen... For accurate, smooth data, other methods using higher order approximation are superior in accuracy.
