Speedrunning is best method of learning

[@BriTheMathGuy]

Glad you think so!

[@sonalichakraborty6830]

It's the best method of mugging up or revising. Not learning bro. No way.

Shorts... Keep them coming.. Thank you for sharing

[@BriTheMathGuy]

I’ll do my best!

MORE MATH SHORTS PLEASE xP

[@BriTheMathGuy]

You got it!

[@xiebowen9796]

In fact, if using the trick that you have introduced in your another video about the integral of inverse function, it will be faster.

[@BriTheMathGuy]

You might be right!

[@krupt5995]

What I do is adding and subtracting 1 and then using product rule

[@taaha4532]

Thats called integration by parts

[@dr.rahulgupta7573]

Sir , By using DI method , or tabular integration method ,this problem can be solved in less than 26 sec .

[@senatorpoopypants7182]

The trick really is to imagine dx as a variable I'd never think of that

[@mastershooter64]

I played it at 2x speed and integrated it in 13 seconds _ez_

[@emanuellandeholm5657]

Ridiculous way to solve this integral: substitute u for ln x => Integral of u e^u du. Solve this integral using partial integration. Back substitute.

[@OptimusPhillip]

First time seeing integration by parts for a function that isn't a product of two functions

[@user-lh5hl4sv8z]

I mean it kinda is

[@GlorifiedTruth]

Who is this Ellen X? Was she related to Malcolm?

[@notsodope834]

How does he write backwords in opposite orientation

[@Srilashmyi]

Can you help me please, how to solve integral f(x) dlnx. If you saw this please reply to this comment as soon as possible. Its very urgent

[@irrelevant_noob]

i'd still continue until i crammed that all into " ln( k (x/e)^x ) " with k > 0... :-B

[@NonTwinBrothers]

Bprp could do it faster

[@loyalfriend5471]

Will it work for every question

[@esolsen25]

wait are you writing all of this backwards too so we can see it?!

[@PASHKULI]

No, the video is mirrored. He is not a lefty.

[@Peter_1986]

My guess is that he records himself behind a transparent board, and then mirrors the whole video.
That method would definitely _work,_ so it is a very plausible method.

[@hossam181v7]

Bro that is so confusing 😕 go alot slower and explain where EVERYTHING came from and why i am new to calculse😭

[@hossam181v7]

Calculus* I even spelled it wrong 😭😭

[@bensmart2829]

does this guy have to write backwards for the camera?

[@Bodyknock]

Yep, he’s doing all his equations backwards.

[@madhusudanlm]

I forgot about calculus and observed him writing backwards. This is some amount of dedication! 👏 👏 👏

[@mathewmetcalfe3063]

Zoom!

[@BriTheMathGuy]

🚀🏎

[@mathadventuress]

I think you mean xlnx not ln x

[@irrelevant_noob]

where?
