Replies 4 Views 1K P Show that (1)^n * (n/(n1)) is divergent Last Post;I think the OP's problem here might be with the way the "$\dots$" notation is used in mathematics, to indicate a sequence (in this case the sequence of factors to be multiplied) by listing the first few terms and (if the sequence is finite) the last few terms, leaving it to the reader to mentally fill in the rest (on the assumption that the desired pattern will be clear)= 5\times4\times3\times2\times1$$ That's pretty obvious But I'm wondering what I'd need to use to describe $$$$ like the facto

So, first negative integer factorial is $$1!= n(n1)(n2)(n3) (1) Do this nonrecursively using a for loop (it shouldn't call itself) Paste the code below def factorial ((n2)!)/(n!) = (n2)(n1) Remember that n!

Factorial, in general, is represented as n!, which is equal to n*(n1)*(n2)*(n3)**1, where n can be any finite number In Python, Factorial can be achieved by a loop function, by defining a value for n or by passing an argument to create a value for n(read as n n n factorial) is defined as n! To compute factorial(4), we compute f(3) once, f(2) twice, and f(1) thrice As the number increases the repetitions increase Hence, the solution would be to compute the value once and store it in an array from where it can be accessed the next time the value is required
