Calculus- Lesson 8 | Derivative of a Function | Don't Memorise

[@InfinityLearn_NEET]

Derivatives are used to derive many equations in Physics. It is used to determine the speed or distance covered such as miles per hour, kilometre per hour etc. To learn more about Calculus, enrol in our full course now: bit.ly/CalculusBasics_DM To watch more videos related to Calculus, click here: bit.ly/CalculusBasics

@@InfinityLearn_NEET Ma’am I had a doubt in the 2nd Video. Ma’am, the instantaneous speed should be root of 5 as if we go by that at 1/2 length, PE=KE. We can write it as 1/2mgh = 1/2mv^2 This implies that v= root of (GH) So ma’m if we approximate acceleration due to gravity to be 10 then ans = root of 5.

[@adeelfitness4993]

You are absolutely amazing. For the first time in my life I understood this concept and uses of derivatives. Thanks a lot. Keep it up

[@b43_pranjalvyas76]

I feel this is the best video on KZbin for lucid explanations

[@atta-ur-rehmankhan4641]

i am extremely impressed by your teaching methods. You are simply awesome.

[@sankalpfauzdar1535]

Mam you are angel of knowledge.. study basics of subjects & concepts are excellent

[@mutualyc385]

As we know that dy/dx is referred to instantaneous rate of change of y with respect to x but in the case x = 0 it is not possible to find out the derivative because it does not exist due to absence of tangent line..... By the way loved your way of explanation and animation of this topic♥️

[@joyneelrocks]

Also if we analytically try to solve this, in the end, we get: f’(x) = lim(∆x -> 0) |∆x| ÷ ∆x Therefore: If x > 0 => f’(x) = 1 If x < 0 => f’(x) = -1 And, if x = 0 => f’(x) = Infinity

f(x)= abs x f'(x)=(f(x+h)=f(x))/h f'(x)=(abs (x+h)-abs x)/h which can be written ((abs x+abs h) -abs x)/h, so abs x and -abs x cancel each other lim h->0 (abs h)/h=(abs 0)-0=0 if x=0 the derivative is still 0

I really appreciate with your channel awesome explanation with details and in very smooth way but i have one suggestion for you please can you make a video on PDE (Partial derivation) because in most engineering program are solved based on that and if you are doing about on that so it's very helpful for all engineering student so plz think on that way Thank you

[@shashisuryawanshi173]

No, we cannot find the derivative of y = |x| at x=0, since we can draw more than 1 tangent at x=0 to the graph of y = |x|, which would imply that function can have more than one slope at a particular point and thus the derivative is undefined.

[@antoniusdaivap7759]

The graph isnt even a slope its like a sharp v. But I dont know either

1:43 If Delta x is less than zero than it must be x not minus delta x on x axis instead of x not plus delta x. Correct me if I am wrong.

[@swayamjha3988]

i am willing to understant the nature of cosmos please accept my request and make videos on general relativity and quantum mechanics The way you teach I will definitely understand it easily and able to work further on my research

[@harshsrivastava31]

Which class are you in because genrel relatativity is a very complicated theory and quantum physics is much more weirder than that. General relativity includes 4d, so it would be very complicated for this channel, on the other quantum mechanics is much more complicated than general relativity and according to me, you should learn it from other you tube channels, these topics are very complicated for this channel. I am currently in class 9 and it took me 2 years to fully understand relativity both genrel and special, when I was in class 6 I started studying it and it took me 2 years when I reached in class 8 I fully understood it from explanation to derivation. So don't feel I can't do it if it seem very complicated, I also took 2 years. AND SERIOUSLY MY FRIENDS THESE TOPICS ARE UNFIT FOR THIS CHANNEL

the derivative or differentiaion is the instantaneous rate of change and is the slope of the tangent of the curve

[@abdulwaris8309]

Very well explained.

[@armstrongtixid6873]

It doesn't exist for the end thing? Because from the right hand side, if you imagine this as a graph, the slope as approaching x = 0, is 1, while from the left, it is -1? Just a guess. It's like a limit that is different from the - and + sides.
