• You can use SQR with any type of graph.

• You cannot use SQR inside a program.

• You can use SQR with a graph produced by a multi-statement connected by “:”,

even if the multi-statement includes non-graph operations.

• When SQR is used in a statement that uses a display result command (^) to

draw a graph, Graph Adjust parameters are applied up to the display result

command, but any graphs drawn after the display result command are drawn

according to normal graph overwrite rules.

k Rounding Coordinates (RND)

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 To round the coordinates at the points of intersection of the two

graphs drawn on page 146

Use the same View Window parameters as in the example on page

146.

1. After graphing the functions, press 1 (Trace) and move the pointer to the first

intersection.

e ~ e

2. Press 2 (Zoom) 6 (g).

3. Press 3 (RND) and then 1 (Trace). Use e to move the pointer to the other

intersection. The rounded coordinate values for the pointer position appear on

the screen.
