Determine an estimate forsusing Simpsons Rule with 10 intervals.

I'm not sure about this one at all if anyone can help?

Thanks.

Care to share what you've tried? For reference, Simpson's Rule (and in particular, Composite Simpson's Rule).

Set up your subintervals and then just apply the formula. - June 8th 2012, 05:42 PMReckonerRe: Simpsons Rule anyone?
And, by the way, note that we can evaluate this integral without using numerical methods. Let .

Sorry, I'm eager to learn but I'm afraid I'm a complete beginner.

I've managed to teach myself some basic calculus but I really need walking through it step by step. :( - June 9th 2012, 04:25 AMReckonerRe: Simpsons Rule anyone?
People are usually more willing to help if you demonstrate that you've made an effort to solve the problem. An easy way to do this is to show any work you've done. And if you can't figure out where to start, you should give specifics on what you don't understand about the process.

I'll set it up this time, though. We want to split [0, 5] into 10 subintervals. That means each subinterval would have to be units wide. Therefore, the values separating the subintervals are

Now we put these values into the formula.

Now evaluate the integrand (which I'm calling ) at each endpoint. - June 9th 2012, 02:04 PMsrhRe: Simpsons Rule anyone?
Thanks, I'll give it a go.

First of all here is a link to the Simpson's Rule with shown examples.

Secondly this integral can be solved directly using substitution rule.

Let then du=16tdt and .

Since x is changing from 0 to 5 then u is changing from 7 to 207 and your integral now is

Now, if you are still don't understand Simpson's rule than divide interval [0,5] on n=10 subintervals with length

So, :

Your function is

Therefore, by Simpson's rule approximation is

Plug values and calculate. For example
