Vector Dot Product and Vector Length

[cglg1234]

you write vectors differently from the way i was taught, got confused for a bit there, either way understandable and helpful :)

Thank you so much!! You are part of the reason I passed my first semester in year 10 :D

What software is that

[pellevinken]

@sahayester Have you found out what software that is?

[thesilversavers]

@pellevinken Its some simple drawing application like Paint. I believe he made use of a tablet and wrote on it.

@sahayester that's a program coming with an external hardware called drawing pad. So he draws it on the pad and pad sends drawings to pc instantly =)

Hmm, so I understand the definition of dot product and vector length. I understand the dot product is a scalar, but does it have any other meaningful "substance", or is it simply a mathematical tool used in other definitions?

I have to raise an eyebrow at some of your comments regarding multidimensional spaces, especially the one about length somehow changing after 3 dimensions. Anyone with an understanding of how length works in 2 and 3 dimensions knows how it works in n dimensions, it's all the same.

finally i get it! thanks so much.

reminds me of discrete maths I did in my first year software engineering degree. lol good old days.

True!
