Edexcel A level Maths: 11.4 Reverse Chain Rule (Integration)

Pearson A level Maths, Pure Year 2 Textbook (11.4)

In this video I explain the two forms of the reverse chain rule for integration, how to spot when the reverse chain rule can be used and examples/exam style questions on integrating functions using the reverse chain rule for integration.

You are probably the only one on the whole internet who has explained integration in a very intuitive and easy-to-understand way. Thank you!!!

I will never forgive the man that disliked this video

[sarahsandy]

helpful!! PLEASE do stats and mechanics year 2 I am finding it hard :(

[Phantom_Kraken]

Me: [failing math]
Zeeshan: “come this is no place to die”

[tomwilkinson]

Dude you're actually a life saver😂 can you become my maths teacher?

[lovelle]

Just found your videos and they are helpful, like i'm in a real classroom. Thank you so much for teaching us!!!!😭😭

[DeKevers]

Absolutely insane stuff, thanks I now love integration

[Jack-mkvy]

Your videos are extremely helpful!! Thank you !!

[albertsalimov]

Professionally executed and most helpful

[beenasalman]

Best teacher ever! Love the clear explanation, thank u!

I definitely prefer the u-sub approach of form 2 (especially regarding the last example question with the sqrt() on the bottom. I think for form 1 the approach makes sense but it becomes too much of an algorithm for form 2 and to me at least that is not how it should be.

[hassanmadani]

Can you show us how to solve differential equations by integrating factor?

[_llby]

Thanks brother ❤️❤️❤️....your videos are life saver ❤️❤️❤️

Couldn’t the 6th question be form 1 if you apply tanx identity and make the integral negative?

[sam_po]

this might be silly question, but where does the -2 come from in -2sin2x when you do dy/dx for the first question at 8:35? why would it not be 2cos2x?

[outlaw]

best teacher even better than my school teacher

[_ozare]

how did u get -2sin2x from dy/dx of sin2x? 17:50

[ditidhutia]

hw do u integrate this question : integration of sec^2 x (1+tan^2 x)

[T_T_S]

Very clear explanation. Thank you sir.

[FaizanA-mhpd]

Sir what's the general rule for integrating A^x ?
E.g integral of 2^4x
