Prove that

Proof so far.

Given , let (or some other positive values that I haven't figure out yet)

Suppose that , I need to show that

Now, I know that , so that

But how would I go from here? thanks.

If we restrict so that , then

Therefore, if

So,

See here for a very nice paper on epsilon delta limits
