Non-linear functions II Flashcards
1
Q
What do periodic functions represent?
A
A cycle or basic pattern of behaviour during a period which is repeated
2
Q
What is the period?
What is the amplitude?
A
Period: The horizontal length of each repeating pattern
Amplitude: Half the vertical distance from minimum to maximum values
3
Q
What is the continuous model which is equivalent of the geometric growth equation?
A
Nt = N0.e^kt
Where t= time
4
Q
What kind of transformation can logarithms to base e do to exponential equations?
A
Transform them to linear ones e.g. y= a^x –> y= e^kx
5
Q
What do exponential curves describe?
A
Processes that accelerate or decelerate over time
