Thanks for the video! I had doubts on this topic.
❤❤❤❤❤
Thank-you 😊
wow, this guy has alot of exes
I don't understand, what happen if I just use df/dx and df/dy instead of the partial one?
your explanations are so good, it helps me a lot! but i wanna ask, what if the CED values is "undefined"? it is means that the goods are not related too? Thank you
Nice and simple ty!
wasted my 4 min thanks
Got my final exam on Monday... should've started watching these videos after the first lecture. These videos are so much clearer than any lecture I've had all year.

Thanks!
thank you for teaching me reverse cursed technique
If the narrator cannot pronounce Chinese names correctly, he shouldn't be narrating.
Yeah I really like how you broke down the problem. Breaking a big problem down into smaller parts really makes it easier for a lot of people. Then all you had to do is just add them up after that and then you have the answer.
Really helpful, Thank You !!
"don't romanticize alexander" how about you don't tell me what to do.
It still doesn't make sense. Is America essentially saying it does just because. Then using it just because logic. It's like saying the sky is blue because the water is blue. What a surprise that was a septic concept when I was growing up.
this was mindblowing
A light-mile is a time A lightyear is a distance Light travels at 186,000 miles per light-186000miles Light travels 1 light second per second (which is a little shy of the distance from earth to the moon) Light travels a distance of 1 light second per Light-186,000 miles In a further twist, we can even say Light travels a distance of 1 light second every light “light second” A light “light seconds” is the time it takes light to travel the distance of 1 light second which is … 1 second But seriously what this cT axis does is makes the 45-degree angle of light on the grid no longer a hypothetical illustratration of how much space pairs to time, but makes it an exactly reconcilable scaling of the 2
where is the normal force? similar example with the bowling ball shows it 3 videos later
I didnt know it was that easy???
Christian old testament is related to the Hebrew Bible but they are not the same exact texts
I don’t have too much of a background with algebra or calculus. I don’t understand why we are using estimations. 5:41 it’s straightforward but i’m confused

3:39 I have a name for this number! >:D When translating 10,1101 to words, I call it "Two Nib en-five" My system for speaking binary numbers out loud actually works on quadruplets of bits, so it's pretty similar to hexadecimal. "Nib" is equal to 1,0000 and it functions almost exactly how thousands do in decimal. It doesn't have detail by itself, but it's used to achieve larger numbers. "Two Nib" is equal to 10 * 1,0000, or 2 * 16. "Two" is still equal to the quantity of 2. Quantities from "Zero" to "Seven" have the exact same names, actually! The next number essentially use the same words, just with a small prefix. Instead of "Eight" through "Fifteen", the names go "En-zero" through "En-seven". The "En-" prefix stands for "enhanced", and it determines whether or not the leftmost bit inside the quadruplet is active. 0101 = "Five" (no prefix, the leftmost bit is a zero) 1101 = "En-five" (yes prefix, the leftmost bit is a one)
How are you supposed to know which of those possible products is the aquaeus solution and which one is the precipitate? It's so over

Is a 59 percent grade bad for the 3rd quarter
should this be called Financial Account?
i cant believe this, my has been on this topic for over a week and here in only 4 mins...
Man.. Nobody can blow your mind like Sal. Listening to him explain this made me feel a bit of fear and nervousness almost. It follows a very common theme in his other playlists. As much as we know, we really don't know very much at all. It's unsettling to realize hiw limited our knowledge is. Especially when it comes to something so innate to all of us. Our history. A history with common themes of war, natural disaster, and finality. Crazy.
😍😍😘😘😘😘
Again and again 😂
i hate math bruh
These graphics are awesome and help so much conceptually, thank you! 🙏
