The number of basis vectors is equal to the number of input variables (seven in this case) minus the rank of the dimension matrix (four in this case). This formula aligns with the Buckingham’s PI theorem9. Since the basis vectors can be computed using Eq. (4) (an algorithm for ...
I modified the formula in excelxor's post so it can identify the sum that is nearest to the target value if there isn't a total equal to the target value. Table of Contents Find numbers closest to sum Find numbers closest to sum - Excel 365 Find numbers in total with a condition Fin...
It used the Chung-Feller theorem, which says that the badness of bracket sequences is uniformly distributed (i.e., there are an equal number of strings for each value of badness), and then showed that the mapping was in fact a bijection from the set of strings of a fixed badness to ...

Relation ≤ less than or equal (not greater) has the following definition: m≤ n ⇔ m = n ∨ m < n. It can be proved that the definitions (1) and (2) are correct: there is precisely one natural number k satisfying the definiens of definition (1) and there is precisely one numb...

But there’s more. Friday’sWall Street Journalhad an article on Japanese anger at Chinese purchases of yen which, according to Japanese government data released Wednesday, showed that China’s yen purchases this year equal $27 billion, more than six times China’s combined yen buying in the...
Because 1 is paired with 10 (our n), we can say that each column has (n+1). And how many pairs do we have? Well, we have 2 equal rows, we must have n/2 pairs. which is the formula above. Wait — what about an odd number of items?
