Determine a Least Squares Solutions to Ax=b 

the diagrams showing the relationship between b, b (projected onto a), and the orthogonal complement to column space of a really helped w visualizing least squares thanks so much!

The best explanation that I found on RU-vid. thanks very much...

this is one of the only explanations i’ve seen that actually makes sense. thank you!!!

You are so good at teaching math

THANK YOU SO MUCH SIR FOR SUCH AN AMAZING VIDEO , IT REALLY HELPED ME , THANK YOU AGAIN

Very helpful indeed

very clear explanation

講的真好🎉🎉

thx

One of your exams is we by I think when you do ax matrix it should become 5 2 -1 not 5 2 1

4:26 Ax= 5,2,-1 not 5,2,1
