Matrix of a linear transformation Example 1.mp4

Find the matrix representation of a linear transformation with standard basis in domain and codomain, Example 1. With reference to David Lay's Text Introduction to Linear Algebra with Application

Thoughtful Person. 
The original problem was T(x, y, z)=(y+z, x+z, x-y) --> on the third column is the mistake, thus leading to a different answer. 
However, when solving the problem you solved for a matrix representation for T(x, y, z)=(y+z, x+z, x-z)
That answer is right for T(x, y, z)=(y+z, x+z, x-z)

Nevertheless, for the original problem  T(x, y, z)=(y+z, x+z, x-y). the matrix representation would be Te1=[0, 1, 1], Te2=[1, 0, -1] and Te3=1, 1, 0].
Te1, Te2, Te3 are columns vectors :) 

Nice job explaining thought. [REALLY HELPFUL]

It's cute how you say "zelo" lol. Helpful video!

Very good, thanks.I also want to know which Note you used?

Wei Ching Quek, Hilarious content, although informative. The writing made the video worth it. Thanks for uploading!

Hahaha lol thank you very much! Teaching with comedy. lol "Zelo" is hilarious. I had to stop watching half way, I couldn't stop laughing.

Shouldn't the component in the 3, 2 position be 1 instead of 0?

ermmm in the question it says x-y as the third column not x-z, why you answering it for x-z as the third column for :S:S:S:S

If it wasn't for this video I would het zelo on my test. Thanks.

Thank you Mr. Zelo lol. It really helps.

@warnick80
Thanks!Good Observation! I carelessly "changed" the questions.

[sannabaty]

with out you i would have zelo, , thnkas bro

[rahulk]

He said it in a easy and nice method and u r mocking have some faith u learnt some thing from him

this is more like chinese version of matrices or what they call macharitrixezus
