Rolle's Theorem

This video explains and provided examples of Rolle's Theorem.

thank you sir...due to this online classes situation...most of my doubts were left unclear...your video was a life saver

2 for the price of 1. Teaching's outstanding, quotes uplifting. Who could ask for more?

[dorikanellos]

Great job as ALWAYS. I love the Differential equations lessons, that’s a vivid example for the sorry examples floating around. D🦅

On the unit circle, the cosine of an angle = 0 at pi/2 or 90 degrees and 3pi/2 or 270 degrees.

[jimyleaks]

the cosine of an angle at 3pi/2 or 270 degrees will be also 0..

[akanshaparmar]

Good explanation .. sir can you pls tell how you solve last ques... Why we will take pi/2 ??

[gaithlame]

thank you . can your explain some examples about generalized Rolle's theorem.

[studytimebyarif]

if a function is combined with trigonometry and exponetial term like
e*x cosx how to solve?

[yeab]

dont you have to use chain rule on function f at 4:08? 

[ThuyNguyen-Tiffastic]

But on the interval of pi/6 to pi/3, there is no pi/2.  Pi/2 is beyond pi/3, thus it's not in the interval [pi/6, pi/3].

I prefer you to Khan. Minimal and complete.

You're a great teacher!! For the fact that I'm learning calculus on my own and I haven't found out yet, how and why is the f '(x) at 4:45 the derivative of f(x)=(x^2 - 2x)e^x. There must be some rule or theorem behind so if someone could tell me it :)

[ThoraxetheImp]

Are the two intervals always 0? Or do they just have to be the same?

[ritobrataghosh]

Hi, thank you and I want to know what are the software you are using to make this video (everything including the graphing, writing, slides and video recording).

[CrimsonGuard]

I don't get the art where he gets pi / 2. Where did that come from?

[arenics]

not only at the slopes the derivative = 0, you forgot about the inflexion points.

[nfsking]

If f is discontinuous at that interval.

[AnkitJainCreations]

Can i ask you how f '(x) = 2x - 3 ?

[kermz]

f(1) = -4 and f(2)= -4....u must add before u substract
