What do periodic functions represent?
A cycle or basic pattern of behaviour during a period which is repeated
What is the period?
What is the amplitude?
Period: The horizontal length of each repeating pattern
Amplitude: Half the vertical distance from minimum to maximum values
What is the continuous model which is equivalent of the geometric growth equation?
Nt = N0.e^kt
Where t= time
What kind of transformation can logarithms to base e do to exponential equations?
Transform them to linear ones e.g. y= a^x –> y= e^kx
What do exponential curves describe?
Processes that accelerate or decelerate over time
