Other Graphing Functions
k k k k k Graph Range Adjustment Function
This function makes the View Window
value. It is helpful when drawing circular graphs.
Example
1. After drawing the graph, press 2 (Zoom) 6 (g).
2. Press 2 (SQR) to make the graph a circle.
k k k k k Coordinate Rounding Function
This feature rounds the coordinate values at the pointer location to the optimum
number of significant digits. Rounding coordinates is useful when using trace and
plot.
Example
1. After graphing the functions, press 1 (Trace) and move the pointer to the first
intersection.
r
To graph = 5sin and then adjust the graph.
Use the following View Window parameters.
Xmin = –8
Xmax = 8
Xscale = 1
To round the coordinates at the points of intersection of the
two graphs drawn on page 128
Use the same View Window parameters as in the example on page
128.
