Drawing a Graph
•If you do not specify a variable name (variable A in the above key operation), the calculator automatically uses one of the default variables listed below. Note that the default variable used depends on the memory area type where you are storing the graph function.
| Memory Area Type | Default Variable |
| Yn | X |
| rn | θ |
| Xtn | T |
| Ytn | T |
| fn | X |
Example | Y1 (3) and Y1 (X = 3) are identical values. |
•You can also use Dynamic Graph for a look at how changes in coefficients alter the appearance of a graph. See
