Euler's Method (introduction & example)

[@wcolesully]

This dude is singlehandedly saving my college career, love you RedPenBlackPen!

[@blackpenredpen]

Thank you. Best wishes to you!

[@benjamaster7]

Hey guys, welcome back to a video on the 100000th thing named after Euler

[@akstudios5450]

Name 100 others

[@jonathanbyrdmusic]

KZbin is actually named after the U in eUler

[@dogukankaradag4690]

You're the best ever!! Keep doing this man....

[@aaaaaa7810]

Best video about Euler's method in all youtube.

[@RaykoF]

Was very pleased to see numerical integration on this channel. Are you planning to go deeper and, perhaps, discuss Runge-Kutta's methods or backstepping methods?

[@nicoletsang8884]

oh my gosh I've watched my teacher's lecture and my textbook which left me pretty much confusion after all, but your video made everything so crystal clear for me now!!! I love your explanation and clear note on the whiteboard! Keep it up!

[@pragunachandrasekara8922]

Best video on Euler's Method in youtube. I wonder why university lectures over complicate simple things like this.

[@TheToolofLight]

Me: Hey bprp, wanna go see a movie ? bprp: 3:51 Inspired by that peanut comment

[@nicholasleclerc1583]

Anex_ I made a comment on that word too, but for 2:52

[@faanzeonlam3219]

Wish u a great day

[@jgc9199]

Should've came here first. Went through 4 different channels and I was still confused and just looking at the way you showed it I understood it on the first watch. Ty!

[@omarhuda4997]

Wow, excellent timing. I'm doing a computational course around Euler's method.

[@fer-gr8kf]

THANK YOU!! im glad i was already subscribed to you because of another video, cause i knew this was gonna be good!! thanks for explaining so simply and concisely :D

[@bearpowder8807]

This was a fantastic video, im ready to write my code now. thank you.

[@RupeshKumar-hl2jw]

Thank you so much for simplifying the concept.

[@markmanning-o4w]

Ive used a similar method ( tables Po, X, Y, Totals ) to solve several differential equations involving acid solutions in a tub... without knowing Euler's method even existed as I haven't studied Diff.Eq. before. At the time it seemed like a very crude method I was using to solve differential equations; but it worked.

[@sebastianreina4620]

Hi Blackpenredpen let me express you that i enjoy much your videos, i have a little dificult with this integral and many people too. the integral is: integral of (x-2)÷((x)*(sqrt(x-1))*(sqrt((x^2)-x+1)))dx

[@friedkeenan]

I made a program on my calculator to do this

[@ffggddss]

Excellent intro to numerical integration methods! Making clear the reasoning behind the method. If you're willing & interested, might I suggest a followup video on why this method strays from the true solution, and what are the possible remedies (other than just decreasing the step size, which actually makes the solution worse after some point, due to computational precision limitations)? Of course every method misses the mark to some degree; the goal is to minimize the errors. In this case, we start out each step headed in the right direction, but along the way, F(x,y) is changing, so the resulting direction of each step drifts off by some amount. Of course, I realize that this quest is a bottomless pit; it's a matter of just how deep you want to go in rooting out those errors. Maybe go as far as starting into the various degrees of Runge-Kutta methods? Euler's method is good, because it's simple, easy to implement, and fast. And it can give you a real handle on the DE you're trying to solve, when symbolic methods can't be applied. Anyway, just a thought - suitable for framing or wrapping fish, as _MAD_ magazine used to say . . . ;-) Fred

[@sophielee9380]

This is so helpful. Thank you!!

[@rojaandia9372]

wow you are the best, Thank you

[@YLprime]

this channel saves me once after once

[@YLprime]

my math skills=organic chemistry tutor, blackpenredpen and 3b1b

[@DarthVader-fu2nr]

That DORAEMON into!!!!!

[@DhanashreeSanjayIngale]

you such a nice guy.....totally in love with the way you teach concepts

[@xyd8653]

this is so clear, thank you!

[@rob876]

If you have y' = F(x,y), then you can derive y'', y''', ...etc. This will give you more accurate values for y1, y2, etc. using y(x+h) = y(x) + hy' + h^2/2! y'' + h^3/3! y''' + ...

[@JAS45678]

演算法跳出這個 講的非常清楚 學生時期能看到這支影片就不用這麼辛苦了

[@pollofrio2301]

Explained it so well

[@minheebae4897]

GREAT explanation!!!!

[@stevethecatcouch6532]

And remember, Euler did it all by hand, but still accomplished more than any two of us combined.

[@zulfur2452]

He was even blind for some time.

[@shapirogensichwa]

Easy to figure out compared to rest if his work

[@madihaamanat7366]

Excellent explanation..👍

[@boagokeetshabe1506]

Thank you soo much!!

[@AnuarPhysics]

Great explanation! Just one question. Which mic is that? :O

[@benslimaneyoucef9422]

Very great Sir

[@abdulalhazred5924]

so you could do it like this in js: function euler(target, step, point, foo) { while (point.x 3 * point.x + point.y));

[@drcrash_]

thank you so much

[@christopherokon6596]

How did you solve the differential equation?

[@MagzhanZhengis]

Thank you brother

[@TheKennethLeung]

thank you for the tutorial!

[@planckvanilla8997]

can you also explain the finite elements method?

[@godknifetube]

Many thanks!

[@marceloavila87]

Great explanation, I really liked it. I just didn't get it how you got the y=f(x) from dy/dx. What are the steps you have to follow to solve the dy/dx in order to find that answer y=f(x)?

[@blackpenredpen]

I will do that in another video. It's called the first order linear diff eq.

[@ayman9174]

very helpuful thnx a lot

[@gustavomarcelo7250]

Given dy/dx , at the end we want to find y value, right? All numerical integration is to find y?

[@josh_up]

0 dislikes ... It was awsome bro!

[@catalinadavid5953]

thanks!

[@s.a3898]

How did you get the actual equation at the end?

[@jeanlucas2834]

Best lesson ever in this topic!! Could you make a video about Runge-kutta method? RK4 if you permit me ask. I'm doing a project about it and I need to understand the theory behind it.

[@hawraaraheem2449]

Why we use one step in euler and more steps in Taylor what's that means

[@shruutisurana5728]

Anyone else who heard the doraemontheme song playing in the background in the very beginning

[@ShenghuiYang]

Implicit methods coming soon ;-)

[@PianoBoy-my4ne]

Can you give a proof of the Basel problem?

[@el-hech2889]

Legend

[@CyrusGates]

Good video brader!

[@Adam_mohammed_]

Why the lecturer is holding Pikachu ball 😂😂😂😂?!

[@zapaya_guy]

It's his mic

[@nicholasleclerc1583]

2:52 You said: “Y_not[0]” I heard: “Why not ?”

[@josh_up]

😂

[@imperialrecker7111]

it is actually Y_(naught)

[@borg972]

can you somehow put a bound on the reminder?

[@LeZinZin95]

Trapezoidal method next :)

[@darpan6882]

Sir your looks awosome

[@nick45be]

Great explanation! Can you make a video on backward euler's method? On youtube anyone explain it good 😢

[@10erlangga]

Y not is basically why not 😂

[@MIMI-CO]

i love the doraemon in the background

[@HarshRajAlwaysfree]

Is it for high school students Cuz its sounding not familiar Maybe I need rest

[@corbincox7985]

Super challenge- Show how to solve (2x) to the (x+5)=x to the x

[@anjelpatel36]

What?

[@HarshRajAlwaysfree]

U use too much Doreamon music It works

[@thechirpination7455]

fire

[@clyde1820]

Hey bprp, Can you solve x^x=y for x?

[@alejandroramirez5987]

Check fematika vid

[@ericagracesanchez2414]

👏

[@Crazylust]

I was expecting Black Pen Red Pen...not Green Pen. lol

[@areejmakhamra4016]

You must be patient and organised 😅😅

[@bobengelhardt856]

The Method seems kinda' obvious - had nobody thought of this before Euler?

[@bobengelhardt856]

@dbf2017 Fafalios --- No, I hadn't. But that's putting the bar as low as it can go. I'm not a math-y and I certainly don't remember any if the diff-eq stuff I had in a course 60 years ago. It does seem that someone who was a mathematician and who worked with differential equations would have come up with this before Euler.

[@ffggddss]

Maybe it was just a question of "getting around to it" - calculus itself was still kinda young, and differential equations even more so. Fred

[@l3igl2eaper]

Now do the same problem with the RK4 method! hahaha.... haha...... ha..... ugh.

[@Brekstahkid]

Woo

[@shubhamg9495]

Green pen HmMmMMMmMMMmMMMMmMMMMMmMMMmMMMMmMM.

[@rohunse5555]

First!
