k k k k k Graph Range Adjustment Function
This function makes the View Window
value. It is helpful when drawing circular graphs.
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.
1. After graphing the functions, press 1 (Trace) and move the pointer to the first

Example
To graph
Use the following View Window parameters.
Xmin
Xmax = 8
Xscale = 1
Example
To round the coordinates at the points of intersection of the
