Summary
The important information in this chapter is summarized below.
Graphing Summary
Ordinate -
x-coordinate
Abscissa -
y-coordinate
Cartesian Coordinate System
-
Rectangular Coordinate System
-
Divided into four quadrants by x- and y-axis
Logarithmic Coordinate System
-
One or both of the scales are divided logarithmically
-
Semi-log graphs contain linear x-axis and logarithmic y-axis
-
Log-log graphs contain logarithmic x- and y-axis
Linear functions are usually plotted on Cartesian coordinate graph.
Exponential functions (y = ex) are usually plotted on semi-log graphs to
provide a straight line instead of the resulting curve placed on a Cartesian
coordinate graph.
Power functions (Y = ax2, y = ax3, etc.) are usually plotted on log-log
graphs.
