Re: value of functionI think the set will be infinite. does anyone has anything else in mind? #4 20121121 04:01:03
Re: value of functionyes for n=2, [n]=2 but when n=1.6, [n]=1 #7 20121121 05:21:57
Re: value of function
That is true. You can even plot it to see that the range is R (ie. the reals). The limit operator is just an excuse for doing something you know you can't. “It's the subject that nobody knows anything about that we can all talk about!” ― Richard Feynman “Taking a new step, uttering a new word, is what people fear most.” ― Fyodor Dostoyevsky, Crime and Punishment
