7 MARK Hard Integration Question | A Level Maths

[@HasanMUTD]

Posting this after he gave us a Cambridge step entrance question😭🙏🏽

[@NeilDoesMaths]

I'm deadddddd. Gotta keep you guys working hard

[@redbepis4600]

OR: put the x^2 on top as x^-2 then pull an 9x^2 out of the square root as 3x. Now you'll have x^-3 on top and sqrt(x^-2 - 1/9) on the bottom. Sub u = x^-2 -1/9 and its easy from here

[@NeilDoesMaths]

Interesting take

[@OsmanHamza126]

gonna substitute myself back into bed after this one

[@NeilDoesMaths]

After all that integration the brain was fried

Remember this question from my year 6 SATs. Teacher was stuck on it so I taught her how to do it

[@NeilDoesMaths]

Your teacher is boogin frfr

[@rishabhtiwari2325]

I think it should be 18x in the denominator

[@NeilDoesMaths]

How so?

[@rishabhtiwari2325]

@NeilDoesMaths oh no you are absolutely right it was my mistake in integration of 1/sqrt(x). Sorry

[@HectorTheShred]

Nine???? I thought it was NOINE

[@NeilDoesMaths]

Sorry NOINE

[@AlaraDoesArt]

As a year 9, I’m so confused 😢

[@ilovemyma7112]

Probably cause this is yr 13 just a guess tho

[@Ojisgay]

If you weren’t then you’d probably be a genius or something😂

[@dakitowithred]

@Ojisgay I mean like wouldn't it be impossible for a 14 year old to just grasp what integration is even when they don't have any sort of concept of its application. Like surely someone would have to have taught them what it is for them to comprehend it.

[@NeilDoesMaths]

Last year I taught a 10 year old this stuff and he got an A* in his exams. It's possible!

[@NeilDoesMaths]

One step at a time Alara! 😂

[@MHB15]

r u bugin?
