Question: Graphs: Some questions require production of a plot. You are welcome (indeed encouraged) to produce the plot using a package (e.g. EXCEL) where appropriate. Part of the assigned mark will be for the accuracy of the plot, and a part for presentation (readability, use of units, title, axis labels, suitable choice of axis ranges, etc.). A “publication quality” plot will get full marks. The plot can be printed on a separate s...
