Proving Binomial Identities

[@benzietsch9024]

Woahhh, thank-you girl at 1:40 for walking in frame. I now know I'm learning from a James Ruse teacher!!

[@chazhovnanian6897]

thank you so much, you have no idea how long ive been looking for a comprehensive proof for these identities

[@benzietsch9024]

Oh ok, sorry. I had not seen that video.
I'd just like to thank you for doing what you do Mr Woo, you're a legend! I'm currently in year 11 but I'm accelerating my maths and am actually completing my HSC Ext 1. this year. I have my mid-course exam coming up and your videos have helped me immensely :) keep up the good work.
Ps. I know this video is old hahaha it just happened to be what I was watching

[@davisthato2133]

[@streamvision145]

You're so good and also seem a nice person :)

A little error. At 7:12 you say 4C2 (which = 6) when the number you circled was actually 4C1 = 4.

why would you choose n and r if you have crappy handwriting? choose n and k like a normal person...

[@tahabashir9405]

rude girl. needs a lesson

[@JW-lp4gu]

It’s just a variable. Stop freaking out and don’t be so rude. Literally no one cares

[@Uthuriel]

@@JW-lp4gu you cared enough to write a comment... now STFU...

Great example of proving the identities, and I as well liked the girl at 1:40. Do not edit her out. That is an advertisement as to Why Major in Math! Cute girls are always a plus in math class.
