Speedrunning is best method of learning
Glad you think so!
It's the best method of mugging up or revising. Not learning bro. No way.
@@sonalichakraborty6830 sarcasm much?
@@mastershooter64 no sarcasm it's the truth my friend 😂
@@sonalichakraborty6830 the comment is sarcastic
Shorts... Keep them coming.. Thank you for sharing
I’ll do my best!
MORE MATH SHORTS PLEASE xP
You got it!
In fact, if using the trick that you have introduced in your another video about the integral of inverse function, it will be faster.
You might be right!
What I do is adding and subtracting 1 and then using product rule
Thats called integration by parts
Sir , By using DI method , or tabular integration method ,this problem can be solved in less than 26 sec .
The trick really is to imagine dx as a variable I'd never think of that
I played it at 2x speed and integrated it in 13 seconds _ez_
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.
First time seeing integration by parts for a function that isn't a product of two functions
I mean it kinda is
Who is this Ellen X? Was she related to Malcolm?
How does he write backwords in opposite orientation
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
i'd still continue until i crammed that all into " ln( k (x/e)^x ) " with k > 0... :-B
Bprp could do it faster
Will it work for every question
wait are you writing all of this backwards too so we can see it?!
No, the video is mirrored. He is not a lefty.
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.
Bro that is so confusing 😕 go alot slower and explain where EVERYTHING came from and why i am new to calculse😭
Calculus* I even spelled it wrong 😭😭
does this guy have to write backwards for the camera?
Yep, he’s doing all his equations backwards.
I forgot about calculus and observed him writing backwards. This is some amount of dedication! 👏 👏 👏
Zoom!
🚀🏎
I think you mean xlnx not ln x
where?
