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.

Pay thousands of pounds to learn of a shovel head for a tutor, actually learn for free off RUclips, 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 :)

[@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! :-)

[@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!

[@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.

[@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 :)

[@amberriley7633]

This helped so much thank you!!!!

[@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.

[@evamorley30]

I finally understand it! Thanks :)

[@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!

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).

[@manicmillennial3287]

Your handwriting is very neat

[@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))

[@anthony1003]

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.

[@tanij407]

2 horws before the exam thanks

[@ExamSolutions_Maths]

Hope it went well!

[@ew12345671]

Is that formulae for area in the C2 formulae booklet

Wasn’t square root of 5-1=2
