The Tangent Line and the Derivative (Calculus)
Вставка
- Опубліковано 13 лип 2024
- In calculus, you’ll often hear “The derivative is the slope of the tangent line.” But what is a tangent line? The definition is trickier than you might think.
Tangent lines are important because they are the best way to approximate a curve using a line. We can then use the slope of the line as a way to measure the “slope” of the curve.

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 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.
"If you don't mind, I'd like to on a tangent and touch on an important point." lol
i love the effort you put to make the audience understand the concept of tangent crystal clear.
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 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 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.
thanks a ton for the awesome explanations and for making the videos available on UA-cam
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!
I just want to point out the sound design, I've never seen an educational video pay attention that. It was amazing
This is so helpful and clear.it really saved me half and hour reading the textbook!
Squeaky clean explanation with succinct live demonstrations. Perfect teaching method!
Best explanation in UA-cam. Made things so detailed and easy to understand. More such videos please. Thanks
This was simply amazing! I think I found my new favorite channel! ❤
This is great video I had ever seen. You opened my mind!!!
greatest teacher I've encountered on UA-cam. thank you so much
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..
Verry Verry good videos.
Thanks to Socratica team..........
WOW! This is incredibly well done.
A clear and comprehensive explanation enhanced with an extraordinarily good use of graphics.
Sir, your class is far above excellent.
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! :)
I love how it's so clear to understand!!
This is so well explained. Thank you :D !
great video format , encourages the viewer to think, it's like a game , so creative , really really loved it
One subscribe from India. Really your explanation are amazing.
You really answer all my freaking questions about tangent line
Thanks and I'll promote your video
very easily and neatly explained. Thanks
I love it! It's a crystal clear !
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.
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.
I think this is the greatest explanation of a tangent line to a curve I've seen so far
thank you! This Video was fabulous
Thanks A lot for making all my concepts clear!
Amusing,I really wanted such a video from somedays.I think it is the better channel for learning the fundamental....
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. :)
The best ever explaination of derivatives. Absolute perfection.❤❤❤
Great work! Thanks a lot ✨
Finally best channel to learn Mathematics. Keep adding more advance topics..........
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 have conceptually explained it very well ,hope you will upload more videos
This is awesome, the best I saw on this
Thank you so much for the great explanation !! I will have an exam after two weeks, and needed this clarification!!
Woah bro, u're such a legend at explaining.. plus the visual video is really super helpful ❤💙❤
Awesome! you made it simpler
Thanks very much. Such an awesom video.
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😂
Great explanation I love it mas clear pa sa clear
thankyou
it helped me a lot
Thank u so much ♥️
Finally got what derivative and tangent line is
Perfect explanation👌
It makes a better approaching to understand concept better
Very Good Explanation.....
this was so helpful
Explained Superbly..
this was rlly well explained
Such a useful video!
One word. Awesome!
Quality stuff!
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 🇮🇶
thanks! very clear and enlightening;
Excellent!!
please, more videos about calculus
superb information. please keep more videos on calculus. i want know about subject
Excellent!
I wish that my first college math class explained it this way. Nice job!
really, great ... enjoyed so much... i 'll never mind subscribing.
thank you!
Great video man 👍👍👍
Thanks very much
Not going to skip adds cause you deserve it. Thank you very much
Thank you kind Socratica Friend! We appreciate your support! 💜🦉

just perfect......awesome.....just too perfect....loved it.....
Awesome video …., 10 STAR ⭐️
shared! like the idea of project 7B
This channel make me a better person ^^
superb content
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
Great videos! Could i ask you guys something? Could you gives us more of a basis on math talking about Analytical Geometry and René Descartes? Thanks
Marvelous!
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
Avoids division by zero, but needs monads, which havnt been developed until middle of 20 century and overcomplicated, good replacement...
Thanks a lot!
Thank you so much it really helped me underatand. and i hope you reach your goal i also subscribed. Though is been 3 yrs
wow. just wonderful
Thank you
Thanks 🙏
very nice > thank you
Could you please add videos on the vast topic of Integration?
It will help more.
Amazing
Sir, i will definitely recommend this channel to my friends.
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!! :)
Wahoooo....great work
Awesome Stuff, if you could do more videos on Definite integrals, Double , triple integrals & Differential equations etc. then that would make your channel crosses your goal (7 billion) ....!!
keep up your good work!
thank you
Animations are amazing.
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.
Extrardinary explaination
Please More Videos .... And Please let me know what is the software you use to get those animation of equation
I NEED MORE VIDEOS! FORGOT MY CALC FROM 9 yrs AGO!!! SHOUT OUTS TO DERIVATIVES L'HOSPITAL!!!
AND*
I WANT TO BE A QUANT!!!
