That’s why math and other complicated topics lose people over time. We are given over simplified explanations which eventually fail us. Instead we should be taught the most accurate understanding. It may be harder to grasp initially, but when it is, will be worth the effort.
I was going to make a video on the subject myself, until I saw this one... The fact that most definitions just talk about this tangent line touching the curve at 'one' point never really satisfied my hunger when looking at graphs. Great explanation, visuals and presentation pace.
I want to thank you guys for your amazing videos; they are very well made! I just sent a letter to the UN asking them to ask other nations to subscribe. Hopefully, they'll send a letter to all nations imploring them to subscribe to your channel!
I really like how you gave examples and then invited the viewer to try to come up with their own definition for a tangent line first. Hopefully you release some new math videos soon. Keep it up!
i think it's better for u to check out the Arabic vocabulary to know it is not great to use a different language from your main while speaking to mate of your country :)
I really love calculus and I understand the concepts, but as I teach the concepts to others, I wonder how it can be put best. This is likely the best video I've seen on introducing tangent lines and it was a great watch. Keep it up man!
Thanks so much Sir , first time, I am capable to understand what calculus actually is . Literally you gives understandable content and helping a lot of students.
I have no idea by what do you mean by write a litter for me I found this channel by my search, and now I just realized it could be on of my best channels I ever found. Creating free iraq 🇮🇶
Very nice. Great video. The truth is that the derivative gives the definition of tangent line, not the other way around. For pedagogy purposes I think it's fine to tell students that the derivative is the slope of the tangent... as a way to get start since students start with some kind of intuitive "feeling" of tangent. But the idea that derivative is "defined" to be the slope of the tangent is a misconception. The derivative is what it is. The tangent is defined as the line going through a point on the curve with the derivative of the curve at that point as its slope.
Thank you so much!! We're so happy you've found our channel. When you share our videos with your friends, that really helps us grow. We really appreciate it!! :)
The derivative is the slope of the tangent line right? So how can it be that the slope of the tangent line of y=x^2 = h+3 ( see 10:00) while the power rule gives 2x for the derivative?
Leibniz the co-founder of calculus gave the correct definition of a tangent line ie it touches a curve at 2 adjacent points separated by dx in the x direction and dy in the y direction, so it is dy/dx = the derivative or the hypotenuse of a right triangle = (dy^2+dx^2)^1/2 this avoids division by zero. a single point cannot determine the direction of the tangent but dy/dx does
Hello! This is truly a very good explanation of what a tangent really is. However, I could not help but notice that at 8:37 you said that in the formula m=dy/dx, dy and dx are differentials. I am sure you are aware of the following point but for the perfectionist viewer: In the derivative formula dy and dx ARE NOT DIFFERENTIALS. What holds is: f(x)'=(d/dx)y, where (d/dx) is an operator that changes f(x)=y. For the differentials: dy=f'(x)dx, which clearly does not mean that dy=f'(x)dx since dx can be 0. This might seem unimportant but there are a lot of instances in which it is crucial. Interesting fact: Feynman, when young, invented his own symbol for the derivative just because he did not like Newton's notation: (dy/dx) because it commonly leads to the above misconception. Cheers!
I always had an interesting way of visualizing tangents. I think of the function like a path or road and the point is like a car driving in the road. The tangent is the direction of the exact moment that the car is going.
Great video, but one mistake is at 6:03. The sinc function i.e. sin x / x ==> 1 when x =0. Mcclaurin series can be used to compute f(0). f(x) = sin (x)/x = [x - x^3/3! + x^5/5! ....] / x. ==> f(x) = 1 - x^2/3! + x^4/5! .... now we can see that we f(0) = 1.
I think I figured it out. The tangent line will eventually touch the curve at point (3,9). Therefore, the x value of point P (which is currently h) will either increase or decrease to 3 (it increases in this case as P is closer to the y axis). With that assumption, substituting h for 3 in the slope equation (m=h+3) gives you 6... Might not be the 'right' way but it gets you there in this case :)
*I could go off on a tangent (yep it's not just u who can, has, and will lol) for the stakes of the intention addressed through ending this video.* But I must say this is an explanation I didn't realise I was looking for :)
I love how you went over misconceptions of what a tangent line was first before giving the definition of it. Great video. :-)
Exactly.
That’s why math and other complicated topics lose people over time. We are given over simplified explanations which eventually fail us. Instead we should be taught the most accurate understanding. It may be harder to grasp initially, but when it is, will be worth the effort.
Great explanation. Calculus is fun when you actually know what's going on
Yeah mostly we don't know what are we doing 😂😂
Realest coment
My Calc professor taught the same way but his way was too complicated that I got lost lol. That’s why I am really happy someone did it this simple
i love the effort you put to make the audience understand the concept of tangent crystal clear.
"If you don't mind, I'd like to on a tangent and touch on an important point." lol
I was going to make a video on the subject myself, until I saw this one... The fact that most definitions just talk about this tangent line touching the curve at 'one' point never really satisfied my hunger when looking at graphs. Great explanation, visuals and presentation pace.
I just want to point out the sound design, I've never seen an educational video pay attention that. It was amazing
I want to thank you guys for your amazing videos; they are very well made! I just sent a letter to the UN asking them to ask other nations to subscribe. Hopefully, they'll send a letter to all nations imploring them to subscribe to your channel!
Now there is a guy who knows how to get things done. :) :)
Socratica he only knows how to get things done if the UN. comes through otherwise he gets nothing done.
I really like how you gave examples and then invited the viewer to try to come up with their own definition for a tangent line first. Hopefully you release some new math videos soon. Keep it up!
Thank you so much. The definitions with visuals made the Tangent Line and the Derivative easier to understand and appreciate.
I think this is the greatest explanation of a tangent line to a curve I've seen so far
This is amazing, it made me understand the maths we take at school at a deeper level. Now it makes much more sense to me, thank you!
greatest teacher I've encountered on TH-cam. thank you so much
Sir, your class is far above excellent.
iam here from egypt wait for ur videos more than any of the lectures at my faculty of engineering ........keep going.......... :)
check out the
English Grammar Lessons
i think it's better for u to check out the Arabic vocabulary to know it is not great to use a different language from your main while speaking to mate of your country :)
nour khaled i already speak Arabic
i'm sure dude
We are so glad you are visiting us from Egypt! We dream of visiting one day! Thank you for watching and for your kind message. :)
Great vids. I really hope you don't stop making them. Specially next semester that I'm starting calculus
Thanks! We'll be making *many* more Calculus videos in the coming months.
where is the calc 3 and linear alegbra ones..
Finally best channel to learn Mathematics. Keep adding more advance topics..........
Squeaky clean explanation with succinct live demonstrations. Perfect teaching method!
A clear and comprehensive explanation enhanced with an extraordinarily good use of graphics.
I really love calculus and I understand the concepts, but as I teach the concepts to others, I wonder how it can be put best. This is likely the best video I've seen on introducing tangent lines and it was a great watch. Keep it up man!
Sir, you may not believe that I have already thought of it in my school life. Thanks for this wonderful video. You really deserves like and subscribe.
Verry Verry good videos.
Thanks to Socratica team..........
This is amazing... Best explanation for tangent lines I have watched so far...
You're so kind, thank you for saying this! It really encourages us to make more videos.
Thanks so much Sir , first time, I am capable to understand what calculus actually is . Literally you gives understandable content and helping a lot of students.
The best ever explaination of derivatives. Absolute perfection.❤❤❤
This is so helpful and clear.it really saved me half and hour reading the textbook!
One subscribe from India. Really your explanation are amazing.
The great video made me consider subbing, and the end sealed it. Well done
WE GOT ONE!!!
We're so glad you've joined us! :)
thanks a ton for the awesome explanations and for making the videos available on TH-cam
Probably the best video I have seen in my lyf. Damn you touched so many points.
You really answer all my freaking questions about tangent line
Thanks and I'll promote your video
I have no idea by what do you mean by write a litter for me I found this channel by my search, and now I just realized it could be on of my best channels I ever found.

Amusing,I really wanted such a video from somedays.I think it is the better channel for learning the fundamental....
The sound effects are good because they make you follow along. Easy to get lost in math
I wish that my first college math class explained it this way. Nice job!
It's amazing to see how to get deeper and deeper to the definition of tangent! Remind me how little I know about first principal😂
Best explanation in TH-cam. Made things so detailed and easy to understand. More such videos please. Thanks
very easily and neatly explained. Thanks
great video format , encourages the viewer to think, it's like a game , so creative , really really loved it
Thank you so much, it made me, a thirteen year old, understand it very clear. (I'm Chinese)
We're so glad you're watching, Emily!! :D
This was simply amazing! I think I found my new favorite channel! ❤
please, more videos about calculus
shared! like the idea of project 7B
I NEED MORE VIDEOS! FORGOT MY CALC FROM 9 yrs AGO!!! SHOUT OUTS TO DERIVATIVES L'HOSPITAL!!!
AND*
I WANT TO BE A QUANT!!!
Dx/dy 4 lyfe
I love how it's so clear to understand!!
Not going to skip adds cause you deserve it. Thank you very much
Thank you kind Socratica Friend! We appreciate your support! 💜🦉

This is great video I had ever seen. You opened my mind!!!
Sir, i will definitely recommend this channel to my friends.

The derivative is the slope of the tangent line right? So how can it be that the slope of the tangent line of y=x^2 = h+3 ( see 10:00) while the power rule gives 2x for the derivative?
It makes a better approaching to understand concept better

this avoids division by zero.
a single point cannot determine the direction of the tangent but dy/dx does
Avoids division by zero, but needs monads, which havnt been developed until middle of 20 century and overcomplicated, good replacement...
Could you please add videos on the vast topic of Integration?
It will help more.
math is fun whenever u can visualize it
Thank u so much ♥️
Finally got what derivative and tangent line is
Amazing
Great explanation I love it mas clear pa sa clear
Thanks A lot for making all my concepts clear!
Thank you so much for the great explanation !! I will have an exam after two weeks, and needed this clarification!!
WOW! This is incredibly well done.
Good video. Why are people on the internet better than professors at university?
I love it! It's a crystal clear !
sir , you have conceptually explained it very well ,hope you will upload more videos
This channel make me a better person ^^

This is awesome, the best I saw on this
Plz Upload more topics of calculus.........
really, great ... enjoyed so much... i 'll never mind subscribing.
thank you! This Video was fabulous
This is so well explained. Thank you :D !
Perfect explanation👌
Very Good Explanation.....
I always had an interesting way of visualizing tangents. I think of the function like a path or road and the point is like a car driving in the road. The tangent is the direction of the exact moment that the car is going.
So my definition is that the tangent is the “acceleration” of the point at a given moment. Just to throw physics in the mix
For the final definition 9:18
Great video, but one mistake is at 6:03. The sinc function i.e. sin x / x ==> 1 when x =0. Mcclaurin series can be used to compute f(0). f(x) = sin (x)/x = [x - x^3/3! + x^5/5! ....] / x. ==> f(x) = 1 - x^2/3! + x^4/5! .... now we can see that we f(0) = 1.
Extrardinary explaination
this was rlly well explained
Awesome! you made it simpler
Explained Superbly..
thankyou
it helped me a lot
this was so helpful
Where did the 6 come from. It seems as though it just appeared. Amazing video btw! 😊
I think I figured it out. The tangent line will eventually touch the curve at point (3,9). Therefore, the x value of point P (which is currently h) will either increase or decrease to 3 (it increases in this case as P is closer to the y axis). With that assumption, substituting h for 3 in the slope equation (m=h+3) gives you 6...
Might not be the 'right' way but it gets you there in this case :)
This helps more than school
Awesome video …., 10 STAR ⭐️
Why does when h approaches 3 the m also approaches 6? How? 10:09
Woah bro, u're such a legend at explaining.. plus the visual video is really super helpful ❤💙❤
One word. Awesome!
LIFE SAVER! عمو بحبك❤
Thank you so much for this! Teaching myself just for fun...
Some videos are not as clear
We love to see people learning because they're curious!! Thanks for watching!! 💜🦉
Quality stuff!
Pls keep posting....
Great work! Thanks a lot ✨
superb information. please keep more videos on calculus. i want know about subject
*I could go off on a tangent (yep it's not just u who can, has, and will lol) for the stakes of the intention addressed through ending this video.*
But I must say this is an explanation I didn't realise I was looking for :)
Please More Videos .... And Please let me know what is the software you use to get those animation of equation
In 6:42. How does the left hand and right side limit are not equal? (according to the graph) maybe im confused . Thank you.
If they are not equal then there is simply no limit
Such a useful video!
superb content
Thanks very much. Such an awesom video.
Amazing explaination
7:04
Isnt dy/dx is supposed to be 0 ?
