This visualization saved me some serious time. Thank you
I got to know something which my teacher didn't taught. Thank u sir
Omg why so much hate on a math video, last less than 4 min
Thank you very much. This video helped a lot!!!
I tried, but I can't even watch Khan Academy for three minutes because the way he constantly repeats himself drives me absolutely nuts.
Thank you that super helped me!!! :)
Very useful! Thank you!
Relu is non diffrentiable wali post se ayya hu! Thanks mahesh brah
Thank you !
such a vivid desciption
Thank you
but in the definition (f(x+h) - f(x))/ h we will approach it only from one side right. Then How the derivativecan not be defined????
Thx
Thnk uh
Can a non continuous curve still be differentiable? For example if you had a line of gradient 2 that jumped but still continued to have the same gradient after the jump, would that still be differentiable?
i think i get what you are saying. by jump perhaps you mean gap? If you are visualizing a gap than this scenario isn't identical to what was present in the video. In the video, Sal concludes that the slope on one side is radically different from the other. but what is the slope of a non-existence point?
for differentiabilty to exist it is important that function should be continuous
but how would it be a continuos line if it jumped? part of it would be vertical, so one x value would equal multiple y values. Making it not differentiable
Can we say it is derivative on the endpoints?
Weierstrass function==> continuous and non-differentiable everywhere.
Brownian Motion ==> continuous and non-differentiable everywhere.
thx
🏆
nuh uh, what if you had the line y = 2x for -5
No, a line can't just "jump". what you just typed out would be two separate lines. If you tried to view them as one line then the problem would be at x=0 because y=0 AND y=34. so unless you connected them (making an undefined slope.. a vertical line). then they must be viewed as they are graphed. Two separate lines
hi
I Have a Question (more like confirming),.......so, there are situation where c can be continuous but not differentiate, Then the only Situation I can Guess for Differentiable is to be true is ALWAYS a straight line(a Linear Function, No other Polynomial function), .........or do we have another example
cubics and quadratics are continuous and differentiable too, by induction all polynomials are
Couldn't finish his video. Please refrain from repeating multiple times
Your videos would be half as long if you didn't unnecessarily repeat everything you say 3 or 4 times.
don't hate, appreciate
If you ever teach you'll learn that you often need to repeat the same thing more than once for people to pick up on what you say. If you want someone who teaches calculus in a more straightforward way try PatrickJMT.
bamtakethat at least he posts good videos, specific to the topics. Pre cal was easy as shit to find videos for. Calculus is not as black and white. Great reference.... pretty much every engineering (with internet access) student alive today appreciates your videos.
+bamtakethat
and you wouldn't be watching his video if you weren't dumb and needed someone to re-teach the material to you.
He does that to make the information stay in your head.
I think it will be better if the screen is more colorful or white rather than full black.
Its hard to watch
