Finding absolute and approximate errors

Given the approximation series of the logarithmic function below,

(I’m not sure how to express this equation so I had to take a picture of it, sorry)
I want to write a function, called error comparison, that determines both the absolute and relative errors of the approximation as a function of the approximation order, n, and the value of x.
[abserror,relerror] = error_comparison(x,n)
abserror= abs(x - n)
relerror: abs(x - n) / min(abs(x), abs(n))
any suggestions on how to continue?

"Your plot labels should be..." seems to show, that this is a homework question. Please mention this explicitly, because homework question require a different strategy for answering: If a complete solution is posted, you cannot submit the homework without cheating anymore.

Try and write your equation first. If you don't know how, please read the getting started part of the documentation, and ask a more specific question in this forum. This looks like homework. It is generally frowned upon to ask other people to do your homework.

Now you should implement the formula as a function. Now there are two alternatives: Either create two for loops to vary n and x, or insert the loop over n inside the function foir the stimation of ln and let this function reply the values for 1:n.
If you get explicit problems with the implementation, please append them to your question by editing and mark this by a "[EDITED]" tag in the text.
