Hi,

Can you solve the Riemann Hypothesis for the next video? I'd appreciate the answer!

I endorse. The mathemaniacs require a sacrifice.

Hey Kamal I have a suggestion for you: int from zero to infinity of ln(x)*e^x/(cosh(x))^2

[@xanterrx9741]

I Love your videos I hope you get well and produce more content for us.

[@darthTwin6]

You made that look almost easy! Great vid!

[@raghavendraPi]

😁😁 after a long time, nice one

[@zunaidparker]

You know what comes next...plug it back into the original equation to see if it works ;)

diff equations are the best!

Which aap you are using to make videos?

[@neg2sode]

I suppose he mentioned in his Q&A video that the app being used is the built-in drawing app for Samsung tablets.

Hey bro, do you study astrpohysics rigth? Would not you like to make videos about that any time? Great video as ever

[@maths_505]

I've recently ventured into AI now given the state of academia plus the socioeconomic state of the world rn. I'll return to it later though, but if there's anything I'd like to make videos on its quantum mechanics, especially now that I'm studying grad school qm.

[@sebastianlopezgiraldo21]

@@maths_505 Oh yeah it´s true, I also study astronomy and the academy it´s not son friendly. It would be amazing you do it, because there are not lot of channels of qm so riguruos on youtube (almost are of divulgation that it´s ok too). Thank you and I love your channel

[@A.Hisham86]

Why didn't you just assimilate the constant? I found y= A sinh^1(x) + B(x)sqrt(x^2 +1) + C :)

[@zunaidparker]

There are only 2 constants ie 2 degrees of freedom. You are introducing an extra degree of freedom that doesn't exist in the original equation, your B parameter is not independent of A.

[@Harshit-w5z]

try it with exact differentials/solution by inspection

[@viktor-kolyadenko]

Вы не проверили решение u = +/- 1. Хотя в 2:47 это соответствует A = 0.

Why not sec ?

[@salkabalani1482]

Good job. The only potential snag I see is at time index 2:08 you defined your constant of integration as ln(A)/2. This necessarily means that you assumed that A0, which is not necessarily correct assumption. ln(0) is undefined. Of course, for values of A

[@alnfsyh9403]

Hi, I'm still a new learner.
But why did he say ln(u²-1) instead of
ln(Abs(u²-1)).
Then if 0

[@munibzain1966]

The constant if integration can be any number. And ln(A)/2 can indeed be any number. The range is the entire real axis while the domain doesn't actually matter, since the integration constant is the function ln(A)/2 not A itself. Which means that regradless of the initial conditions, A will always turn out to be greater than zero.

[@giuseppemalaguti435]

u=dy/dx...(1+x^2)uu'+x=xu^2..(t=u^2)..dt/(t-1)=2xdx/(1+x^2)..ln(u^2-1)=ln(1+x^2)+c...u^2=k(1+x^2)+1..u=dy/dx=√(k(1+x^2)+1)...poi si integra
