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.
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.
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.!

I've been struggling with maths this time am going to nail this n6
Thank youuu 🥺🥺
Thank u sooo much
How do you know when to use integration by substitution and substitution by parts ?
You have no choice but to practice loads of integration to build up the intuition to know whether to use either of those techniques.
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 ;)
The second one is a lie that one with the e^3 its e^4 instead
ISN'T it -c when you use brackets
What module does this come up in at ALevel? Is this part of c2?
+Ijaz Sultan Generally C4
are you Ross Geller? lol
5h before paper 3 :D

is this the order in which we should choose our u and dv/dx?
@@kainatmalik8437 Yes.
Could you quickly explain this for me I’ve never heard this method thanks x
