 Author Comment/Response Ann 09/27/08 12:41pm Hi, When I want to check if the results of an expression are an integer or not, I do the following: Expression: Root of 3n^2+6*n+4 Lets call this K Then I take the table of this expression with n is 1 to 1000. I'll call this M M = Table[K, {n, 1, 1000}] I want to know whether these numbers are integers or not. IntegerQ[M] But then I get always the output False. But I want to know for every result if it is True or False. Perhaps it has something to do with the fact that I put a list in IntegerQ (with the brackets {}). (If I want to know if it are Prime Numbers or not, I input PrimeQ[M] and then I do get for every result True or False) What do I have to do? URL: ,
