MHB Numerical Integration Scheme: Interpolating Polynomials Explained

AI Thread Summary
The discussion centers on the challenges of understanding interpolating polynomials and their associated errors, specifically in relation to the composite Simpson's rule, which is exact for polynomials up to order 3 and has an error term proportional to h^4. However, the forum's moderation policy prohibits assistance with questions that contribute to a student's final grade, emphasizing the importance of academic integrity. As a result, the thread was closed to prevent potential cheating. The original poster has the option to contact a moderator for further clarification if the question is not related to a graded assignment. The focus remains on maintaining a fair academic environment.

I am struggling to understand interpolating polynomials and their errors. I have a problem off of a study guide here:

I understand that the composite simpsons rule is only exact for polynomials up to order 3, with error term proportional to h4. Is this the same case? A detailed explanation would be much appreciated, as I mentioned I'm having a hard time grasping this subject. Thank you

Hello Lwooley90,

The attached image indicates that this is a graded assignment, and we do not knowingly help with problems which contribute to a student's final grade as per rule #6, which states:

Do not cheat. Teachers expect questions that form part of an assessment that contributes towards the final grade of a student to be the work of that student and not the work of others. For that reason, MHB policy is to not knowingly help with such questions. If a question presents in such a way as to suggest that it falls in this category, a Moderator will Close the thread (with an explanation as to why the thread was closed). The original poster can always send a pm to the Moderator to discuss the situation but if the Moderator is unconvinced, then the thread will remain closed. When a Moderator is certain that a particular member is attempting to cheat, that member will be banned and the offending thread removed. Where possible, the institute at which the member studies at will also be notified and a copy of the thread provided. This may sound harsh but the fact is that MHB places a high premium on academic honesty and integrity.

I am now directed by MHB policy to close this topic. If this question is from a past exam or for any other reason is not actually a graded assignment, please let me know and I will reopen the topic.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
