Logarithmic plots are useful when the data you're plotting varies over many orders of magnitude. Logarithmic plots can also highlight certain functional relationships
|plot command||functional relationship|
In lecture I will show (1) why each of these functional relationships appears as a straight line in the corresponding plot command and (2) how to estimate the values of the constants from a graph, in order to estimate as an explicit function, given a few data points.
You can derive these formulae from the log-linear relations instead of memorizing them. For example, you can derive by exponentiating both sides of .
