I'm not getting what it means by "naked eye convergence."
I'm re-reading the explanation and looking at the first example, but I still can't get it.
Help!

Oh and also, can someone explain how to do the relative error?
I'm doing the first example, and I'm not getting the value.

For "naked eye convergence", the idea is to look at two pieces of
evidence.

1. In the upper of the two plots, is the partial sum indistinguishable
from the original function?
2. In the lower of the two plots, is the error small at every point?
[Warning: on the vertical axis of the error plot, check whether there
is "10^{-3}" or something like that, to indicate the scale being
used.]

If the answer is "Yes" to both questions, then we say that "naked-eye
convergence" occurs.

For some functions, it will *not* occur.
