This section is an overview of the CONICS Icon. To select this icon, highlight it and press l or
press 7.
The initial CONICS screen allows you to choose from various conic functions, including
rectangular, polar or parametric form. You may use BN to select the equation of the function in
accordance with the type of graph you want to draw. Once you have chosen the conic function you
would like to graph, enter the coefcients of the function and then press u(DRAW).
In the Conics modes, when you press y(G-Solv), although you are still graphing a parabola like
in the Graph icon, notice how the vocabulary and options have changed to be conic specic.
2. For example, you can now examine the line of symmetry for this parabola and the equation of
that line will be displayed. To see the line of symmetry, press w(SYM).
You can continue to analyze different areas of this graph and the line of symmetry will still
be displayed.
