- factorial - Why does 0! = 1? - Mathematics Stack Exchange
The theorem that $\binom {n} {k} = \frac {n!} {k! (n-k)!}$ already assumes $0!$ is defined to be $1$ Otherwise this would be restricted to $0 <k < n$ A reason that we do define $0!$ to be $1$ is so that we can cover those edge cases with the same formula, instead of having to treat them separately We treat binomial coefficients like $\binom {5} {6}$ separately already; the theorem assumes
- Who first defined truth as adæquatio rei et intellectus?
António Manuel Martins claims (@44:41 of his lecture quot;Fonseca on Signs quot;) that the origin of what is now called the correspondence theory of truth, Veritas est adæquatio rei et intellectus
- trigonometry - Why are angles in degrees converted into degrees . . .
As an example, I downloaded some GPS data from my camera the other day in which I found numbers like $4215 983 $ This turned out to represent $42$ degrees and $15 983$ minutes If you go to a particular latitude and longitude on Google Maps it will show the latitude and longitude both in degrees with a decimal fraction and also in degrees, minutes, and seconds with a decimal fraction
- complex analysis - Show that the function $f (z) = \log (z-i)$ is . . .
Ok but the result ends up being the same, $u_ {xx} + u_ {yy}$ is never becoming zero since it is $\frac {x+y-1} {\sqrt {x^2 + (y-1)^2}}$
- When 0 is multiplied with infinity, what is the result?
What I would say is that you can multiply any non-zero number by infinity and get either infinity or negative infinity as long as it isn't used in any mathematical proof Because multiplying by infinity is the equivalent of dividing by 0 When you allow things like that in proofs you end up with nonsense like 1 = 0 Multiplying 0 by infinity is the equivalent of 0 0 which is undefined
- What does it mean to have a determinant equal to zero?
Your answer is already solved, but I would like to add a trick If the rank of an nxn matrix is smaller than n, the determinant will be zero
- What are the criteria for bad faith questions?
The main criteria is that it be asked in bad faith ;-) I'm not entirely insincere: The question is rather how can we tell that, and a big part of the answer is "context"; it's not mainly the question itself
- Como calcular el area de la superficie de un huevo con calculo
Quiero aplicar el cálculo conocimiento en esta pregunta, pero mi conocimiento sobre esta área es limitada Sólo sé la información básica acerca de cálculo, por ejemplo, mediante la integración para calcular el volumen de un objeto Ya he buscado información relevante en línea durante muchos días, pero todavía tengo ni idea
- Funções Sequências (Functions Sequence) - Mathematics Stack Exchange
Contudo, se $d$ é um divisor comum a $30$ e $20$, por exemplo, então $a_d$ foi subtraída duas vezes de $2^ {60}$, uma em $2^ {30}$ e outra em $2^ {20}$, por isso tem que se adicionar de volta
- What is the difference between Fourier series and Fourier . . .
What's the difference between Fourier transformations and Fourier Series? Are they the same, where a transformation is just used when its applied (i e not used in pure mathematics)?
