Vector multiplication getting mentioned reminds me of when I tried making a "2D number base". Integers are essentially just 1-dimensional vectors, so you can make a n-dimensional coordinate system that displays coordinates as a single number using m^n digits. Of course, I never got past "how does multiplication work?" and left the idea on the shelf.
thanks a lot. so glad i found a walkthrough on the same book i am using. please put the name of the book in the description so it is easier for others to find your videos when searching as well!
at 8:05, are you using the points given by X or Y? I thought it would be given by Y but then the numerator would be 3 not 1 I believe (for final answer). I'm probably wrong but not sure
Cole, you're good. Great attention to detail! That numerator should be a 3. I'm not going to change any of my videos now, but I will update them if I use them again in the fall. Thanks for keeping me honest!
Shouldn't the example 3 be ?
Correct! I think he did a mistake. How was linear Algebra for you?

from y = mx + b find the distance between two points to this…really is crazy what math has become
amazing explanations. I can't get the material for the life of me but this has helped greatly!

I'm curious about how orthogonal projection are used in specific applications like image processing or machine learning.
good explanation, thanks. can you tell me which book you are using it as a reference ?
linear algebra and its applications 5th edition
Are we allowed to use u • v = mag(u)mag(v)cos(theta) at any point?
