1. AIAHL2.10.1

   Scaling with logarithms

   Using a logarithmic scale to display data spanning a very wide range and to emphasise rate of growth.

2. AIAHL2.10.2

   Linearizing data; log-log and semi-log graphs

   Taking logs turns exponential and power relationships into straight lines, whose slope and intercept give the parameters.
