Vector Basics - Drawing Vectors/ Vector Addition

Vector Basics - Drawing Vectors/ Vector Addition. In this video, I discuss the basic notion of a vector, and how to add vectors together graphically as well as what it means graphically to multiply a vector by a scalar.

You summed down 5 hours of school into 11 minutes. Bless.

here i was trying to get ahead in class by learning vectors then i hear that sound of death at  0:51 and now i cant stop laughing

[patrickjmt]

hah, only parts of it : )

make sure to write your school dean and tell them to put me on the payroll

[patrickjmt]

it does not matter where on the plane they are initially drawn

[patrickjmt]

@vandal2k6 YOU REALLY DO NOT KNOW? STRANGE IS A MATTER OF TASTE, LIKE CHICKEN.

[patrickjmt]

@saharaaaa111222 glad i was able to help!

[patrickjmt]

@JoannaLaurensings i do in the video at around 9:52

[patrickjmt]

wonderful! i was not sure if i was making it clear or not.... at least one person got it : )

I just wanna take a moment here to tell you you've saved my ass in integral calc, now I'm going to use your videos to save my ass in linear algebra. ty man ty

@BlazeLah most students these days suck too, so i guess it all evens out. that is why the good ole usa is rapidly heading downhill.

@TheDatsunKing welcome to the internet. all of these stuff costs money and ads pay for it. or: you can have no ads, but someone charging a subscription fee. which do you prefer?

You're my physics and calculus teacher for the semester. T H A N K Y O U, I  L O V E Y O U.

[patrickjmt]

well, to me, i do not think of it as reflecting about the x or y axis (in general, you do not do this)

i just flip the vector and make it point the other direction

[patrickjmt]

@ian559fresno i used to bore people in person, yes. not any more though.

[patrickjmt]

there is a fair amount of vector stuff

[patrickjmt]

@tarunala9 ha, take a number and get in line

[patrickjmt]

the ones on my white board are two dimensional!

you can have as many dimensions as you want

[patrickjmt]

no, you can think of magnitude of a vector as length ; it is always positive

this helped me A LOT! thank you so much for taking the time to help out us "not-so-smart" people. :) but on a serious note, i am studying privately and i have no teachers, so you help out A LOT! Question:- In my book it says "Illustrate the following equations geometrically" and i have this on:- 3(1 -2). how do i go about this? does it just stretch out?

Again, thank you! I actually like the whole white board thing.

in 11 minutes and 30 seconds, you explained something my teacher at the age of 72 with 50 years experience failed to teach in a whole day...kudos!
