Hi there, so I am currently trying to figure out a question but have come up with 2 different answers and I am just confusing myself more wondering which one would be correct for the following problem.

I will post both parts of work, 1 being solely in MATLAB as it was easy to just copy and past while the other is already written up as it was my first attempt. Hopefully there is enough information here and hopefully someone could give me some advice as it would be appreciated.

Thanks in advance for your time!
