TI-83 Plus Function Graphing 122
• At Xres=8, functions are evaluated and graphed at every eighth pixel
along the x-axis.
Tip: Small Xres values improve graph resolution but may cause the TI-83 Plus
to draw graphs more slowly.
Changing a Window Variable Value
To change a window variable value from the window editor, follow these
steps.
1. Press † or } to move the cursor to the window variable you want to
change.
2. Edit the value, which can be an expression.

• Move the cursor to a specific digit, and then edit it.
3. Press Í, †, or }. If you entered an expression, the TI-83 Plus
evaluates it. The new value is stored.
Note: Xmin<Xmax and Ymin<Ymax must be true in order to graph.
