The Vector Equation of Lines | Multivariable Calculus
Вставка
- Опубліковано 12 вер 2024
- We've likely seen lines in 2D before, but how do we describe lines in 3 or more dimensions? In this video we will come up with a vector equation of lines that nicely generalizes what we've seen before in 2D. Effectively, to come up with an equation of a line you need two pieces of information, a point on the line and a direction vector along the line.

5 minute-video from you yet a million times better than the one and a half hour lecture from my professor...thank you!
WOW.. this is exactly what I was looking for! Thank you so much for explaining what the equations actually mean. Instantly subscribed : )
Hey Dr Trefor, a wannabe physicist here. I just wanna say that your tutorials are AMAZING. Now any person with an internet connection, can access education at his/her finger tips. Thank you so much, you deserve much more subs...

Hello , how are going your studies , are you on the way ?
1 video = few lectures + few handout materials from my professor. Thank you for your share!!!
ua-cam.com/video/XQIbn27dOjE/v-deo.html 💐💐👍
Excellent and, again, UNIQUE approach for the equations of lines! I am really enjoying this series so far!!
The format in your tutorials is nice. I´m axious to see that presentation explaining the combinatorial argument about the sum of N² natural numbers. Thanks for sharing
Stewart's Calculus has a nice amount of interesting practice problems , but feels like a calculus cook book. These videos are excellent in explaining the why
A big fat salute!!! Thanks a lot, that tv vector part was cherry on top of cake 💕
I like the parallel to y=mx+b, the r0 is like a support for the whole thing like b is. And the v determines direction just like m
Thank you for the video. The illustrations were really helpful in understanding the concept
FYI, the 'g' in analogous is hard, as in gust, not just.
In your accent
@@soorian6493 Yeah, and my accent is the correct and only important one. What's your point?
OMG I FINALLY GET IT!!!
love that feeling!
this is exactly what i was looking for.. thanks
thanks for helping me enrich my knowledge of vectors; A-levels will now be a breeze!
Thank you so much for explaining this so well!
Glad it was helpful!
Thank you very much for your nice explanation
wow I understood this right away, thanks!
WOW simply amazing.
What is nice is that the parametric equation of the line extents to 2 dimensions
So good man, you now havw yourself a devout follower 😂
I’m not gonna fail my midterm, thank you!!!!!
Do you have any recommended textbooks or problem sets? I am not in college but would like to practice and learn the courses. However, I found most online material out of date.
I WANTED THIS VISUALISATION SO FREAKING BADD!!!! THANK YOU SO MUCH (Sorry for the caps right there...couldnt resist)
You are awesome .I am really waiting for your videos about vector calculus (line integrals, curl,...).LOVE FROM IRAN😚

Po (point)--> starting from here (0>zero/origin) upto P (point) 3:50
vector from/btw Po and P is V or tV
Vectors r and ro are vectors from origin to the points P and Po resp.

Best.Thanks Herr Dr
Thanks for your videos!
My pleasure!
Thank you Dr. Trefor :)
Thank you very much!
I hope you will make Arabic translation available in your wonderful and very useful videos.
Great video man, super super helpful :D
AMAZING!!
if I get the equation 2x_1+3x_2=0 how do I find the direction vector. im aware the normal would be (2 3) but what's the direction vector? I searched all over google but I couldn't find an answer.
Thx for saving my life XD
Thank you

👍 well done
this is clear af
sir can you explain why cartesian equation of a staright line have two equal symbols and have three terms
Keep up the great work
finallyyyy i get it thanks ಥ‿ಥ
Sir, is it mean that the r node is the point where we start?
to start on the line
🔥🔥🔥
Wowwwwwwwww I got it
great tutorial, but please fix the echo
Yayyyyyyyyy!!!
tnx sr

Why did we find r vector it only gives the position vector of point P .we need to find vector v since it is parallel to line ,equation of line and the vector v is same
