4. Move the trace pointer to the end point of the range for which you want to perform Fourier
series expansion, and then press w.
• This displays a dialog box for specifying the start degree of the Fourier series.
5. Input a value in the range of 1 to 99, and then press w.
• This displays a dialog box for inputting the degree of the Fourier series.
6. Input a value in the range of 1 to 10, and then press w.
• The graph function list appears with the calculation result.
7. Pressing 6(DRAW) here graphs the function.
• This lets you compare the expanded function graph and the original graph to see if they
are the same.
Note
When you press 6(DRAW) in step 7, the graph of the result of the Fourier series
expansion may not align correctly with the original graph on which it is overlaid. If this
happens, shift the position the original graph to align it with the overlaid graph.
For information about how to move the original graph, see "To move a particular graph on
a multi-graph display" (page 11-12).
