Infinity times zero or zero times infinity is a battle of two giants Zero is so small that it makes everyone vanish, but infinite is so huge that it makes everyone infinite after multiplication In particular, infinity is the same thing as 1 over 0, so zero times infinity is the same thing as zero over zero, which is an indeterminate form Your title says something else than. The theorem that $\binom {n} {k} = \frac {n!} {k 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 El resultado de correr el proceso 3 por una hora es 2 barriles de gasolina 3 Todas las semanas se podrían comprar 200 barriles de crudo 1 a 2 dólares el barril y 300 barriles de crudo 2 a 3 dólares el barril. Division is the inverse operation of multiplication, and subtraction is the inverse of addition Because of that, multiplication and division are actually one step done together from left to right
Therefore, pemdas and bodmas are the same thing To see why the difference in the order of the letters in pemdas and bodmas doesn't matter, consider the. 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. Perhaps, this question has been answered already but i am not aware of any existing answer
Is there any international icon or symbol for showing contradiction or reaching a contradiction in mathem. The main criteria is that it be asked in bad faith 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. For the given equation $ax=0$ where $a$ is a square matrix and $x$ is a column vector, why $a$ must be a singular matrix (determinant $0$) in order to have $x. (the general formula of legendre polynomial s is given by following equation
