This is the last paper for this semester. It builds on papers 1 and 2. I like to participate in the process, and I added my contribution. Please add or modify the part I wrote that you find pertinent.
I included papers 1 and 2, but I sent that paper just now to be edited based on the correction made by the teacher. As soon as I get it done, I will include it in this folder. I included for now the one with the correction suggestions from the teacher, so you know what has been done in papers 1 and 2.
