applet has two functions: plotting and finding the exponential function
which best approximates the user supplied data. Use it as follows:
the data to plot and analyze in the Data section. Though the
variables default to x (the independent variable) and y (the
dependent variable), they can be renamed. Renaming them will
cause the graph to be updated. The values are entered one per
buttons work as follows: CLEAR will clear the data, the
plot area and the RESULTS area. PLOT will plot the data
as points. ANALYZE will find the exponential function
which best approximates the data, plot it and display its equation
in the RESULTS area.
plot area (top, right) will show the plot.
RESULTS area is used to communicate with the user. Errors will
be displayed there, for example if the number of values is not
the same for both variables. Information will also be displayed
there. For example, when the user clicks on ANALYZE,
the equation of the regression function will appear there, as
well as the error associated with this function.
