STo make V-Window settings

1.From the Main Menu, enter the GRAPH mode.

2.Press (V-WIN) to display the V-Window setting screen.

Rectangular coordinate parameter Xmin/Xmax … Minimum/maximum x-axis value Xscale … Spacing of x-axis increments

Xdot … Value that corresponds to one x-axis dot Ymin/Ymax … Minimum/maximum y-axis value Yscale … Spacing of y-axis increments

Polar coordinate parameter

TΘ min/TΘ max ... Minimum/maximum T, ΘΘvalues TΘ ptch ... T, Θ pitch

3.Press A to move the highlighting and input an appropriate value for each parameter, pressing Uafter each.

•{INIT}/{TRIG}/{STD} … V-Window {initial settings}/{initial settings using specified angle unit}/{standardized settings}

•{STO}/{RCL} … V-Window setting {store}/{recall}

After settings are the way you want them, press )or

)(QUIT) to exit the V-Window

setting screen.

 

•Pressing Uwithout inputting anything while I(busy indicator) is displayed exits the V-Window setting screen.

SV-Window Setting Precautions

•Inputting zero for TΘ ptch causes an error.

•Any illegal input (out of range value, negative sign without a value, etc.) causes an error.

•When TΘ max is less than TΘ min, TΘ ptch becomes negative.

•You can input expressions (such as 2Π) as V-Window parameters.

•When the V-Window setting produces an axis that does not fit on the display, the scale of the axis is indicated on the edge of the display closest to the origin.

•Changing the V-Window settings clears the graph currently on the display and replaces it with the new axes only.

•Changing the Xmin or Xmax value causes the Xdot value to be adjusted automatically. Changing the Xdot value causes the Xmax value to be adjusted automatically.

•A polar coordinate (r =) or parametric graph will appear coarse if the settings you make in the V-Window cause the TΘ ptch value to be too large, relative to the differential between the TΘ min and TΘ max settings. If the settings you make cause the TΘ ptch value to be too small relative to the differential between the TΘ min and TΘ max settings, on the other hand, the graph will take a very long time to draw.

•The following is the input range for V-Window parameters. –9.999999999E97 to 9.999999999E 97
