Question

How do you use the limit definition to prove a limit exists?

Answer 1

See below

Explanation:

The definition of limit of a sequence is:

Given `{a_n}` a sequence of real numbers, we say that `{a_n}` has limit `l` if and only if

`AA epsilon>0, exists n_0 in NN // AAn>n_0 rArr abs(a_n-l))< epsilon`
