This is not a graphing calculator. Besides, most graphing calculators are able to graph functions, and conics are not functions. You need a utility that graphs conics. The Casio FX-9750G and others have a conics utility. On the TI83/84 Plus you can download an application that draws them.

How do i graph a circle in parametric mode?


The simplest way is
X1=cos(T)
Y1=sin(T)
Set angle unit to radians,
Set the Zoom window to SQR (square), otherwise your circle will look like an ellipse.

Area/volume of a ellipse


I am afraid I do not understand what you want exactly (ellipse, parallelepiped?). The area of an ellipse with semi-major axis a and semi-minor axis b is given by
Area=PI*a*b

My fx-9750GA PLUS wont graph lines, cicles or paraballas


Sure it does! Did you ask it to graph?Here are some screen captures to help you find your way.
To draw functions (regular, parametric, polar, sequences) use the application graph: Highloghted on 1st screen capture. The second screen captures shows you the functions y=f(x). enter a legal expression and press F6 Draw. To set TYPE press the key under TYPE.

To draw conics (circles, parabolas, hyperbolas, and ellipses) use the CONiCS applications. (See 3rd screen ). On 4th capture the equation highlight is one for the parabola. y=x^2

Scroll down or up examining the small graphs. They will show you which equation form to choose.
For the circles

What is the forular/working out of- ellipse with a long axis 2.500mm and short axis .850 (double the 0.425 radius) the area is 1.669 thus the area of the part circle is 0.835. what is the formular


I'm not sure what your ellipse looks like but the equation for the area of an ellipse is given by:

pi times the long axis times the short axis

pi = 3.1416
The length of the long axis is from the center of the ellipse to the outer edge of the ellipse
The length of the short axis is from the center of the ellipse to the outer edge of the ellipse

Hope this helps Loringh
