There was a network issue here that caused the site to only be accessible from on campus. However for various classes of rougher functions (ones with weaker smoothness conditions), the trapezoidal rule has faster convergence in general than Simpson's rule.[2] Moreover, the trapezoidal rule tends to become extremely Please try the request again. Trapezoidal Rule Example It is argued that the speed of convergence of the trapezoidal rule reflects and can be used as a definition of classes of smoothness of the functions.[3] Periodic functions[edit] The trapezoidal

The $x\cos x$ term is negative, so in the interval $[\pi/2,\pi]$, the absolute value of the derivative is less than or equal to the larger of $2$ and $\pi$, which is

Simpson’s Rule This is the final method we’re going to take a look at and in this case we will again divide up the interval  into n subintervals.  However unlike the Trapezoidal Formula Show Answer If the equations are overlapping the text (they are probably all shifted downwards from where they should be) then you are probably using Internet Explorer 10 or Internet Explorer Text is available under the Creative Commons Attribution-ShareAlike License; additional terms may apply.

Thus, if we use $K=2+\pi$, we can be sure that we are taking a pessimistically large value for $K$. The error estimate for the Trapezoidal Rule is close to the truth only for some really weird functions.
