[@brandonfreese3005]

No idea if you are still taking the course but your videos are a big help sir, even ten years on. You take complex things and make them extremely easy.

In data science, hero's either wear capes or are Indian. :D

This is 4th video of yours I have watched. They are all amazing. You are a life saver.

[@casacara]

Didn't expect to be here for ksp modding, but here I am. Thanks!

[@LAnonHubbard]

Thanks for the video. I've been working through Lagrange polynomials today and managed to come up with an interpolating polynomial over 4 data points using Lagrange basis polynomials. Your previous videos have helped me to gain confidence in the terminology, process, etc. This video was fantastic even if it was more of a review one. Thanks for putting these resources up.

[@numericalmethodsguy]

@SpitTanker (x) is the independent variable for the Lagrangian interpolant, the xi and xj are specific points at which y values are given.

[@souravjana8667]

you are great sir.....your lectures helped me to understand the subject in just two days before the exam....thanks a lot sir...

[@sculptedmercedes]

This is just the explanation I've been looking for! Great and clear videos~

[@CodingMazaa]

excellent teacher. I wish I had him in my college days

[@AJ-et3vf]

Great video! I have a renewed interest and enthusiasm in numerical analysis and I love relearning these concepts especially that I have experienced doing numerical computation in Python.

[@theultimatereductionist7592]

Fantastic! Now, please do a video on the Lagrange Inversion Formula (LIF)! Thank you!

[@marianaemmanuel5878]

The greatest mind do share with the community.Thanks for the good contribution in the technology of mathematics Gratefully!

[@jerome_ee6522]

This is an excellent explanation and flow of teaching.

[@CharlieTan84]

Thanks for the video sir. I think you are a great professor! Thank you very much for your contributions to the science community!

[@ColorfullHD]

Clear, simple explanation. Thank you.

[@theultimatereductionist7592]

I love playing around with all sorts of arbitrary interpolating functions: not just polynomials. To fit a given functional form, g(x), to (n+1) given data points (x(i),y(i)) for i = 0 through n, just write f(x) = sum of g(i,x)*y(i) where g(i,x) is a function, depending on i, which has the form g(x) but such that g(i,x(m)) = 0 for each m in 0 through n not equal to i, and = 1 for m=i.

[@cleverclover7]

You are a good teacher. Thank you for posting this.

[@txray3409]

Love his hand writing haha Very good dry erase hand writing skills.

[@garg.shelvi]

your lectures help me understand in minutes.. :) thanks a lot sir . :)

[@priyanksharma4178]

awesome lectures! :D

[@70ME3E]

also, I kinda wanted to know Why does the formula look like this ( a bit of an explanation ), and I was not looking for someone to speak out loud the symbols of the formula while writing it down slowly.. we can kinda see all this when we look at it. oh well maybe I should just look up the proof of it to understand it better x)

[@flameofshadow7734]

Thanks a lot ,sir

[@ab_c4429]

Thank you so much for writing it out. That was the confusing part for me. Again thanks!

[@skulthqidub9959]

What a great explanation! Thank you!

[@aniketparichha7917]

thanks a lot for your simple explanation....

[@MBK90210]

Firstly thanks so much fr the video. Really helps. I was wandering if there is a link somewhere of the notes either written or typed. Would love to print them and have a hard copy as reference

[@sachinkumarprajapati]

thanks for the knowledge, it was very helpful. thanks sir

[@kickthedonky]

realy well done! Thank you from germany! :)

[@numericalmethodsguy]

Good for you. You must go to a tough school and must live in a country which is #1 in everything!

[@DHMathematicaAcademy]

If we have only two points (x_n, f_n), (x_(n+), f_(n+1)) how can i generalize the formula without Summation form

[@chizhang3263]

really helpful!

[@queenofunderland]

.your lectures helped me a lot, thx sire !

[@sanjaykumaryadav3186]

sir will u give us video on hermite interpolation

[@rezelee]

My professor is asking us, why we multiply them by f(xi). I dont know what to answer. Where did that come from?

[@malekebadi9805]

Amazing, thanks a lot.

[@user-yk3sf9is2u]

Thanks for the video! Very nicely explained

Great! Thanks sir..

[@numericalmethodsguy]

See the link in the description of this video.

[@faheemabbas8620]

It was very helpful.thanks sir

[@learninghub_ak]

can u help me with gaussian forward and backward interpolation. maybe some worked out examples

[@numericalmethodsguy]

You will see a link at 07:07 of the video.

[@AnilDewani]

Also, where is the video which shows the example? :(

[@aichatouhami8467]

Thank you so much please i need To understand GEAR method for intgral

[@AnilDewani]

Wow, Thanks a lot sir.

[@kyranwilliamson]

absolute legend! thanks so much

[@yashkumarmaharjan5551]

nice video amazing

[@MexterO123]

Thanks a lot! :D

[@CrispyCyclicCenk]

thanks alot

[@gonebraska]

Dude you rule! Thanks!

[@osm85]

when I solve (180, 1.1438) and (270, 1.1380) using direct method and spline linear interpolationd (using the equation of straight-line, i get differenct answer. is it possible?

[@tongthuymy6672]

In theory, you can have infinite polynomial go through 2 points

[@DebaucherousDaniels]

:) thanks again!

[@rayoaklight]

thank you

[@Cyfkycdrycvkb]

Thank you!

[@panelacosmica6747]

great +10 +fav

[@rashedulrashed8641]

nice

[@saideep025]

that is indian maths....

[@1Pr0digy]

I dont think that it is good to do that in 10th grade. A lot more than just math and english is needed for a profound education. s.a. Alexander von Humboldt.

[@70ME3E]

is calling the number 0 "not" a widely used thing? found it rly weird (my mother tongue isn't English tho) also, if you use Lagrange's name often, why not bother looking up how it is said correctly? :S :S :S sorry for the negativity, just had to say it Peace

[@thenumber5isfly]

im sooo confused
