2 hours of reading and a 1.25 hour class period summed up perfectly in 11 minutes

Awesome thanks

man just dropped a masterpiece of an explanation and disappeared for life

[DenieceNg]

Clear and straight forward explanation with helpful tips. Best video for LaGrange Interpolating so far.

Man I had 30 min to study for my exam and I found this video!! PERFECT!

That is what I called: when someone is a genius algorithm creator and a good teacher. :)

Thanks man. :)

Thank you for the easiest explanation. This is pure gold. I got more in 10 minutes than in the whole semester.

Wow what a co-incident. I happen to be a UMBC student who is taking this class now. I was looking for a video to understand this concept. Great video man. Thanks.

well done jian
an irish student says thank you

praise the almighty that good guys like you exist to aid the mere mortals like us

[dutta.alankar]

Very clearly and carefully explained in as simple way as possible. Many thanks.

Thank you, construction of Lagrange Polynoms seems so much easier with this framework. 

[bensmith]

thanks so much for this dude! helping me even 6 years later!

[nadadoux]

This helped A LOT, you should be making more of that video seriously :)

[SyafiqSyadidulAzmi-bwjy]

no way, the way you teach is really cool and easy to understand.
Im indonesian student and thanks!

AWESOME!!! You are the best! Very clearly explained!! Thanks for simplifying this so well!

[jamesbergeron]

Very nicely done.  Easy to follow and comprehend the mechanics of what is going on.  Thank you

Great video bro. Python teacher straight up just gave us the formula at the start with the giant pi addition symbol and expected us to get it

[fatmanurmolla]

You should make more videos, great!!!

Sorry, I missed the part where you explained what these thing actually are and how they work:

For people still struggling, we build this interpolating polynomial such that if you put in x_1 you get y_1 etc, which means we have to make the Lagrange term for y_1 = 1 at x_1 and also  that the other Lagrange terms are all zero:

like so:

f(x) = L_1(x)y_1 + L_2(x)y_2 + …

f(x_1) = L_1(x_1) * y_1 = y_1

L_2, L_3, ..., L_n all zero.

Hey, Thanks for your great video. I was wondering if you have any other videos about Numerical Method?

Bro thank you, I have a test today, this is gonna help me
