How to do integration by parts | ExamSolutions

[@TheKillerind]

What my lecturer couldn't teach me in 2 hours, you taught in less than 15 minutes.

Hats off to you sir, you're amazing.!

When you go through the second example, you missed out the power of 2 for the x. It should have been x^2, instead of just x. If you use just x, the calculations are much simpler, but with x^2, to differentiate v*du, you need to use integration by parts all over again.

I've been struggling with maths this time am going to nail this n6

How do you know when to use integration by substitution and substitution by parts ?

[@sadmanzaid420]

You have no choice but to practice loads of integration to build up the intuition to know whether to use either of those techniques.

[@rf890]

HEY so when you have a product use integration by parts , when you have something with a square root or brackets use integration by substitution ;)

[@farzanamasois]

Thank youuu 🥺🥺

[@mohsaj7652]

ISN'T it -c when you use brackets

[@zeevariabletv]

The second one is a lie that one with the e^3 its e^4 instead

[@CrescentStarSoldier]

What module does this come up in at ALevel? Is this part of c2?

Thank u sooo much

are you Ross Geller? lol

[@justshan2413]

You should've introduced the ILATE Rule [ I (Inverse trigonometric), L (Logarithmic), A (Algebraic), T (Trigonometric), and E (Exponential) ] when it comes to assigning "u" and "dv/dx". At least pin this for viewers to notice.

[@kainatmalik8437]

is this the order in which we should choose our u and dv/dx?

[@justshan2413]

@@kainatmalik8437 Yes.

[@eleanormustill6315]

Could you quickly explain this for me I’ve never heard this method thanks x
