From the MAIN MENU enter into the GRAPH icon by either moving the cursor to
highlight the icon or pressing the [3] key.
This part of the calculator has a lot of functionality. Stores graphs, up to 20
functions that you use regularly or ‘families’ of graphs where relationships and
special features can be viewed.
All of the ‘Function’ key menus, such as Trace, Zoom, V-Window, Sketch, Graphical Solutions and Graph - Text
are also available. It is also where you can view Graph - Graphs and Graph - Table split screens. The screen is split
vertically, giving very good views of what you have chosen to see.
You can draw equations and in-equations, rectangular, parametric and polar graph types. By selecting [F3] you can
view the different types.
