No, d/d = 1, n ranges from 0 to d.
lim_(n->d) n/d = 1
Then, where the limit isn't the only tool to evaluate properties of a function, here there is a symmetry between the extents. The constant, monotone, positive progression of values is from zero to one. And, the sum of their differences is one. And, the complementary or reverse equivalency function with it, sees a symmetry about 1/2. Thus, it starts from end to beginning, as beginning to end: toward the other extent.
Well my, my, my, that looks just like Leibniz' "naive" notion of an infinitesimal. And, as one of the discovers of the original infinitesimal analysis, these days well known as the integral calculus, his notation of the integral bar S for summation and d for differential matches it quite clearly. So, this kind of notion is at least perfectly familiar to those familiar with the development, of the calculus. And, in the very real, as it were, application of the integral calculus, it is where the differential vanishes but does not disappear, that Int 1 dx = 1.
Int_0^1 1 dx = 1 Int_0^1 1 dx =/= 0
S_0^1 dx = 1
It is for no finite differential that this is so: and for no zero differential, in the asymptotic of differences. And, transfinite cardinals' place in measure theory is that the measure of [0,1] = 1.
There are most certainly infinities in mathematics, and the Universe would be its own powerset, and the reals standardly are a construction, with rules, to support analysis, over the continuum. The linear continuum, then as real numbers, of the trichotomy of all scalar values, has the real numbers as defined to fulfill being both the complete ordered field: and the sequential, the points in a line of the linear continuum. And, from the Infinitarcalcul, there are more of those than standard reals. Even Archimedes, was not solely, Archimedean.
So: add (a positive quantity) to zero, it's greater than zero.
