Good morning. I have a question regarding the correct version of exercise 6.2.1, point (b), from the book, which can be found on page 241, I'm attaching the PDF with the solutions I proposed.
Version 2 is based on the exercise done in class on 10/10/2025; I am also attaching a photo below.
I remain at your disposal for any clarifications regarding the steps I followed to obtain these solutions.
