I calculated the position of this star. The numbers seem to be correct, but my friend said they didn't know why. So today, rather than finding the answer again, I'm trying to fix the explanation. Could you let me know which parts of my notebook are hard to understand? It's okay if you don't know the calculations. I left the question column blank on purpose. I'll only check it during the school's public observation hours. Please choose how you'd prefer to do this: whether we should look at the drawing first, or if I should explain it in words.
