D I Method Integration by Parts

[@josephparrish7625]

I never learned by the DI method so I haven’t been a fan. However, your explanation and organization with a chart have made me a believer! As always, your presentation is very clear. 😊

[@pierotezen4272]

I haven't studied integration properly since 2011, so watching this feels very refreshing and inspiring, thank you and keep the good work!

[@PrimeNewtons]

You're very welcome!

[@jackdinatale7092]

you are the GOAT my friend, thank you

[@낙원행당한무지성거인]

Feel so grateful of learning this great method of Integration. Thankyou again

[@Legend-nw1jh]

I open KZbin to find some useful things for calculas and I found this and your channel 😊

[@coreymonsta7505]

I love your video. Going to show my students this method even applies to these self similarity kinds of integrals.

[@rasraster]

Beautifully and simply explained

[@Legend-nw1jh]

You are awesome 😊 I love your video ❤

[@Chilneun]

thank you sir, your video has taught me this wonderful method in the simplest way possible. i find it very easy to get despite having a very chaotic brain. i wish you all the best. 😊

mr prime newton i wish you were my lecturer

[@saarike]

Just great!!! Thank you

[@abubakarabdulkadir6033]

This channel help me pass any course in my semester, but one thing remain please upload video about RANDOM VARIABLE, DISCRETE PROBABILITY FUNCTION, DISTRIBUTION FUNCTION, and solve problems thank you 🙏🙏🙏

[@jarlenewestney2542]

Thank you so much!!! this is so helpful

[@daacosta]

You're very good boss

the goat💯

[@PrimeNewtons]

Lol. Thanks

[@aloixasinclaire9911]

And if you've multiplied both sides by "dx", why isn't the term "uv" multiplied by dx as well? (btw - you're still lecturing)

[@joshuakarki5894]

It’s not multiplied by dx, that’s the differential of the variable x used only on the literals of integration, which uv is not

[@aloixasinclaire9911]

so that's supposed to be dv/dx ? The division looks like a space and then intended multiplication (which would explain why I didn't see it distributed to the uv term on the right). Thank you for your reply (I'm really just taking the piss for fun - the author of the video knows what I'm referring to :)

[@joshuakarki5894]

@@aloixasinclaire9911 Not really, its just there to indicate that the variable of integration is x. If that isn’t specified, you’d treat all variables as constants including x. Multivariable calculus is where this concept really matters, but for now just know that all integrals need to have a variable of integration, and that’s what the dx is there to represent.

[@aloixasinclaire9911]

Ok thank you! If I ever get as far as multivarianle calculus, then I'll understand why it's in the numerator and not the denomimator...

[@aloixasinclaire9911]

Why did you write a dx times your integral v du? I'm writing this as your still explaining it because I want the answer now!! LMAO (you know what I'm referring to!!)

[@joshuakarki5894]

You gotta integrate the product v du with a variable of integration so the dx serves to indicate that the variable of integration is x

[@aloixasinclaire9911]

Why didn't you start with the second integral on the same line? Oh nevermind - you're still lecturing! Maybe you've got a plan! lmao

[@aloixasinclaire9911]

it would be the integral of 0 times sin x at the six minute mark

[@joshuakarki5894]

At 5:46, yea

[@vashon100]

Why wouldn't it be as he shows? integral of 0 * cos x ?

[@aloixasinclaire9911]

Why didn't you put a plus C in the second integral? (Ok - I'll stop - I think I've made my point ;)

[@PrimeNewtons]

You are cracking me up.
