Hi, I know how to show the following sequence goes to its limit, but i need to do it using the definition, of which i am having trouble, i've started how i should though i think.
Let be given
Let be an integer greater than ...(answer goes here)...
Then for all we have
and that is where i get stuck.
I'm not sure if this definition method of proof is well known so if you would like an example of a completed question just ask. Thanks.
