Trapezium Rule : ExamSolutions Maths Revision

[@AnnieeBubble]

ExamSolutions I did the IB first so only had a few weeks to teach myself A Level Maths after those exams, and basically solely used your videos to do that. I managed to scrape an A in the end which got me into Oxford and that is all down to you and your videos. I have already donated to your website but still really cannot thank you enough!!

[@ExamSolutions_Maths]

Congratulations and thank you for making a donation. I will be writing separately to you.

Woah thank you - im an adult learner going back to do (NCEA Level 3) calculus so I can get into an engineering degree. My online course had me absolutely stumped, they tend not to lay things out very clearly. They show me the trapezium rule (in symbols not words), the question, and the final answer, with no working in between and no reasoning for why each number went where it did. I need to understand things before I can move on otherwise I get far too overwhelmed, I'm not a memorization learner (picture opening a book, not finishing it, leaving it open, and picking up the next book in the series. Eventually the table would become piled too high with books to even think about the one in front of you), but one 9 minute video and you explained this so clearly and concisely, thank you so much 💛

hope you get in!

Pay thousands of pounds to learn of a shovel head for a tutor, actually learn for free off KZbin, thank you very much for this explanation!

[@ExamSolutions_Maths]

Glad to help you.

[@jerrykumar2339]

wow! you are awsome man. I wish all teachers could teach as simple as you have illustrated. good job. keep making more videos :)

[@i_am_gods_child]

thankyou, the formula written down like that is so much easier to remember and apply! got my an exam today (its the morning and im just going over this) so thanks so much!! update: there was a question in the exam about it so this did really help :)

[@a.m826]

I have to respect this man, thank you so much for explaining it to me so freely,,, my teacher on the other hand would just explain some gibberish, this was so helpful. :)

[@Henchmedias]

Really helpful, took a little while to get going as I was just using this as revision but brilliant as a recap. Keep making great videos! :-)

[@salemy300]

Thank you so much for these videos they are so helpful, and have helped mee soooo much for C2! you explain it soo so well!

[@ExamSolutions_Maths]

Salem Y Thank you for using them and any support you give.

[@ZariZari0.0]

Thank you so much .. i missed my class where sir shows us how to do trapezium rule.. but because of you i understood it .. thank you so much :)

[@ExamSolutions_Maths]

No problem. Pleased it helped.

[@Lingard-p4e]

10 years later and its still so helpful

[@chocopie645]

[@ExamSolutions_Maths]

All the best for C2

[@Jackywacky96]

You're doing your maths as level the same as me then? :D

[@Quiyum]

Hello seniors(hopefully) I have my exams soon

[@Quiyum]

and I am repeating ...

[@squitboss3301]

@@Quiyum how u doing ? r u ready ?

[@jg1143]

Thank you so so much, helped for my c2 exam! I missed the classes for this topic and now I finally understand it so well!

[@Leafling2023]

So this is how you do it. When i first saw the formula i thought how would i even work it out or how to but watching this video this is so much better.

[@jysharif]

Missed all the lessons on c2 integration but thank to your videos it didn't matter the fact I missed class thanks for the great work

[@ExamSolutions_Maths]

JY Sharif Good to hear you caught up. Good luck.

[@jysharif]

Thank you

[@mxhsvn_b7866]

I literally love you thank you so much

[@PingPongPuggyBub]

Thank you a million, honestly your site is saving my maths grades :)

[@ExamSolutions_Maths]

Your welcome and I hope it will eventually give you the confidence you need.

[@zyd_zz7588]

Awesome video, but is it possible to make a small video showing how you derived that formula? I'm sure you derived it from the formula of "1/2 (a+b) h" or something like that. Thanks!

[@SuperYtc1]

It's from the formula for the area of a trapezium, which is 1/2 * (a + b) * d (half the sum of the parallel sides, times the distance between them) and basically summing up all those trapeziums. The reason why you have 2(.....) in the bracket is because those widths are used twice, once for the trapezium to its left, and again for the trapezium to its right).

[@MrNaberz]

I found a better way in my opinion How to find width: Width (h) = (b - a)/number of strips Trapezium rule= h/2(first f(x) +2(sum of middle f(x))+ last f(x))

[@sadmanzaid420]

What better way? This is the exact formula based on the Newton-Cotes formula which states that one can find the exact value of the integral as an nth order polynomial.

[@finance123]

thank u so much, u have helped me a lot to save my maths grades

[@ExamSolutions_Maths]

Thanks - that is what I like to hear. Wishing you every success.

[@ew12345671]

Is that formulae for area in the C2 formulae booklet

[@ExamSolutions_Maths]

+Edgar Woodhead It's at the bottom of page 5 qualifications.pearson.com/content/dam/pdf/A%20Level/Mathematics/2013/Specification%20and%20sample%20assessments/N38210A-GCE-Mathematical-Formulae-Statistical-Tables.pdf

[@marquez2390]

Yes

[@gaminginspace7731]

Also when do us h= b-a/n

[@gaminginspace7731]

Wasn’t square root of 5-1=2

[@shazaslm]

Square root of 4 is 2.
