Hi all

I have created this issue on my repository and really need help.

Any ideas about how to solve and implement this exercise in fortran?

If you’re writing a simple program with user interaction, you can ask the user to enter a value of ‘z’ that is in [-1,1] range.

With the user input of ‘z’ and x=3, you can calculate ‘m’ - I think a simple Newton method should converge in a few iterations.

Then determine the summation series involving Greek letter ‘xi’ by adding terms and stopping when the increment is less than EPSILON of the floating-point precision being used.

‘lnx’ is yielded by the Taylor’s series expansion you show.
