The good folks here at Lamar jumped right on the problem this morning and got the issue sorted out. At this point, I think one would be best off computing the uncertainty in the integral based on the uncertainty in the fitted parameters and the formula for the analytic integral. What is way to eat rice with hands in front of westerners such that it doesn't appear to be yucky? Trapezoidal Rule Example 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

In the interval from $\pi/2$ to $\pi$, the cosine is negative, while the sine is positive. The sine is definitely $\le 2$. Show Answer There are a variety of ways to download pdf versions of the material on the site. Check This Out In the interval from $0$ to $\pi/2$, our second derivative is less than $2+\pi/2$.

You can help by adding to it. (January 2010) For various classes of functions that are not twice-differentiable, the trapezoidal rule has sharper bounds than Simpson's rule.[2] See also[edit] Gaussian quadrature Do I have to delete lambdas?

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 These bounds will give the largest possible error in the estimate, but it should also be pointed out that the actual error may be significantly smaller than the bound.  The bound Notice that each approximation actually covers two of the subintervals.  This is the reason for requiring n to be even.  Some of the approximations look more like a line than a this contact form Java beginner exercise : Write a class "Air Plane" Is there a developers image of 16.04 LTS?
