kek OP, it's this kind of apollonian idealization of something as mundane and pedestrian as mathematics that accounts for the low number of successful mathematicians in the UK. Oxford and Cambridge need to stick to philosophy and logic. toppest of keks.

Yes it's real although I don´t really see what the "multiply both sides by dx"-part is for. As far as I can tell it would work perfectly fine just by interpreting y(x) as a 0-form. Mind explaining why you did that?
Also a lot of thing go implicitly in there, like what the integral of a differential form even means, how the exterior deravtive is definied, what the integral over a zero-dimensional surface and so on, so you still have to be carefull if you are not familiar with differential forms.

>>7692621
I'm not going to write a book on differential forms just to show why a simple trick works.

>>7692911
Why would you say ~0? That just disguises the smallness of the error.

>>7692613
Someone please explain

I like

[math] \displaystyle \Delta M_{i}^{-1} = - \partial \sum\limits_{n=1}^{N} D_{i}[n] \bigg[ \sum\limits_{j \in C[i]} F_{ij} [n-1] + Fext_{i} [n^{-1}] \bigg] [/math]

>>7693080
Indeed. You don't need Stokes' (which proof is many pages long and is more suitable in higher dimensions) in this. Simply integrate both sides respect to x. Fundamental theorem of calculus says [math]\int y'(x) dx=y+d[/math] and we know that [math]\int x dx=1/2x^2+e[/math] so [math]y=1/2x^2+c[/math]

>>7690189
1+2+3+4+5+6+7...=-1/12.

Ho yeah.

>>7693131
The fundamental theorem does not say that. It only applies to definite integrals. Also using stokes theorem as opposed to the fundamental theorem is really just one extra step.
The fundamental theorem is just stokes theorem with [math]M[/math] a 1-manifold and [math]\omega[/math] as 0-form.

The fact that the arithmetic derivative has a power rule, chain rule, and quotient rule that look pretty much exactly like the derivative from regular calculus is pretty pornographic to me.

that's the borwein integral
it was originally believed to be an error with the CAS they were using, but it's legit

In general similar integrals have value
>π/2
whenever the numbers 3, 5, 7… are replaced by positive real numbers such that the sum of their reciprocals is less than 1. In the example above,
>1/3 + 1/5 + … + 1/13 < 1
but
>1/3 + 1/5 + … + 1/15 > 1.

incorrect
ln(e^ir)=ln(e^0)
ir*ln(e)=o*ln(e)
ir*ln(e)=o

which means either ir=0 or ln(e)=0 , but ln(e)=1 so thaht means that ir=0 ...put that in the starting exuation and you get
e^0=e^0
