Math is magic, and music is math.

Ever see DIsney's "Donald In Mathmagic Land"?

Seeing it as a kid profoundly influenced my love for numbers.

[velociraptorTheone]

Math tv,u people r doing a great job!

[badnunik]

Very easy to understand, I never liked math when I was younger now I love it! 2 thumbs up!!!

[MsMadame]

OMG!  I see it. Your a wonderful professor.

i think the sum of (2k-1), for k=1 to n, it is equal to k^2 ,instead of n^2.

[danielcohen88]

@Goni8607 nup, because n is the last term.

[0748821365]

@danielcohen88 Verry correct.

It is sm from k=1 to N not k :P

[0748821365]

@danielcohen88 Verry correct.

It is sum from k=1 to N not k :P

[Goni8607]

?!...i think it's a mistake

[novatodeguitarra]

from this you can figure out that if you want to sum the even numbers you just can do this look

if the sum from k=1 to n of 2k-1=n^2 then the sum from k=1 to n of 2k will be this plus the sum from k=1 to n of 1 wich is just n sooo

the sum from k=1 to n of 2k=n^2+n and those are the even numbers also if you take the two out of the sum you get that the sum from k=1 to n of k is (n^2+n)/2 which is the sum of all natural numbers

Oh my god!!!!! I get it now!!! thanks :D

[michaeljimpogi23]

you're the best!!!

[sunshinex1104]

youre awesome !

i wish they could use you as a living textbook , and replace all those other confusing teachers! ^_^ no offence to all the other great teachers out there. but damn! there are those that dont seem to love their job and do their thing;; to TEACH kids & actually make them pass.

teachers should really evaluate how you teach so they can learn some teaching tips. ..haha, now theres an irony !

Thanks for the video!!

[ricesniper]

well for me i had one experience of being a student of a teacher who simply hated her job, but she turned out to be the best teacher i ever had :D

[dompafernet]

I wish I had you as a teacher in high school...

Stay solid, rock on!

[elementoxygen]

It's just great watching your videos! I learn a lot more from you than from some teacher's :).

[NateMan58]

Thanks Mate so much easier to understand than the text books.

[BrocWorst]

Very cool! Thank you

[SailFast13]

THANK YOU SO MUCH!!!!

I USED ALL YOUR VIDEOS TO PREPARE FOR MY BGCSE's

[CindyCat73]

THANK YOU!! Books can't explain in simple terms what you need to know. I can read everything you are saying, but the textbooks ASSUME you understand this math already. ha! Nope! But you sure helped!! THANKS!

[SlimJ1992]

mistake at 3:46 he says it works pretty well for the "sequence of squares" but he is not yet there as he still is on the odd number sequence... but still good vid

[themarman]

Great vid. Cheers

[chopperhead2011]

Math and science pwn all

[GRX13]

Agreed. Almost everything can be expressed in a scientific idea or equation. Pwns history and geography + all other almost useless subjects.

[hallogen38]

Thanks for this vid, helped me alot :)

[Chitownboy1023]

Math is almost like magic.

[rawr68]

math is magic!

[Anonymiusen]

No, its not. And that's the beauty of it.
