There are two main reasons to use logarithmic ... number of widgets over time. The bottom chart of Figure 4 makes it much clearer that the rate of change or growth rate is constant.

Velocity-time ... rate to constant speed. Remember, acceleration is the same as gradient, and acceleration = velocity change ÷ time. To find the distance travelled, look at the area under the graph.

What are the underlying principles of how populations change over ... log of the population, at any particular time, is some constant, times that time. The constant r is referred to as the ...
