I have been hard at work on my MU120 TMA01 PT1 which I have completed today, I must admit this was more of a pain than I thought it would be! All was running well until I hit question 2 part D, where I got stuck on something which happened to be straightforward but took me a fair amount of time to solve. I can't discuss the question at the moment as the TMA deadline has not passed but section 1.7 in the calculator book should give people a good grounding in tackling the question.
Now the TMA is complete I have two gripes. The first is that I cannot submit it electronically, which isn't a massive issue but it is an annoyance as up until now I have submitted all my TMA's in this way. The OU put it down to Maths being much easier to work with on paper than on the PC, which after spending a good 5 minutes trying to find out how to use superscript for the squared symbol in Microsoft word I realised is probably true. My second gripe is that you cannot search the PDF texts for this course. I know a lot of students like to work from textbooks but I personally enjoy the freedom of PDFs and the ease of reference come TMA time. Unfortunately as I learned today the old nose in the book and search method has to be used now and again, this is because the MU120 texts are written using a special piece of software to deal with all the mathematical characters which when converted to PDF, is unsearchable (Arrgghh!).
