Hey I just wanted to thank you your videos really helped me through my math classes back in 2009/2010. I remember when I first clicked on your channel you only had a few hundred subs now you have over a million! I am not the best at math or biggest fan of algebra but I have to admit Like terms are probably one of the more interesting/not so bad algebra to do.
i'm not sure if this was already expressed in the video, but it bears repeating: The cart only starts braking at the bottom of the slope, on the straight stretch. respect
Is it common that braking forces are proportional to velocity? The force of friction is dependent on weight alone (no velocity component), to my knowledge. The drag force from air (or liquid) is proportional to the square of velocity (v^2). I never considered k*v, so does this apply to disc brakes, for example? And where do I find real world values of k?
Hi , I’m just watching this video and I have a test in a two days. I would like to ask could you possibly show me how to do these problems as an example using Gaussian Elimination it would really help . 1. X + Y + Z = 3 X - 2y + 4z = 5 3y + 4z = 5 2.) 2x + y + 3z = 1 2x + 6y + 8z = 3 6x + 8y + 18z = 5 3.) 12x +5y +z = 0 23x + 4y - z = 0
Adebisi I did but see that’s a basic one , I’m trying to see how to solve for one that doesn’t have a variable . I have mastered all my problems but the ones in my comment 😞
You taught me so much throughout my calc years. Now we need your help with some fluid dynamics introduction good Sir
Patrick I believe you can fill the massive void for dynamics videos. We need you man its rough out here.
I guess Im pretty off topic but do anyone know a good site to stream newly released movies online?
@Clayton Spencer I use FlixZone. Just google for it :)

The cart will never stop. No matter how long it takes, v will never reach zero.

Patrick you are the goat. thank you for doing what you do.
Love these vids

sir which drawing tablet and software you use for making video lecture
Will you eventually go through special relativity and quantum theory?
Hi , I’m just watching this video and I have a test in a two days. I would like to ask could you possibly show me how to do these problems as an example using Gaussian Elimination it would really help .
1. X + Y + Z = 3
X - 2y + 4z = 5
3y + 4z = 5
2.) 2x + y + 3z = 1
2x + 6y + 8z = 3
6x + 8y + 18z = 5
3.) 12x +5y +z = 0
23x + 4y - z = 0
Focusing on the First problem,
First set up your matrix with the coefficients
Oh I just realized all this would be so much easier to show over a video. Hey Patrick!
Adebisi yess it really would be if really appreciate it
@@TheNaenae02 I just realized he already has a video on it. Look up Gaussian Elimination on his UA-cam page

good video lecture
what would I do without you
I Appreciate You ^_^
I can teach mathematics for free and provide one on one coaching
