The calculator casio CFX 9850GA was not turning on..

Hello,
Turn calculator [ON]. If you do not see the menu icons, press [MENU]. Use the arrow keys to highlight the [GRAPH] icon.
An entry screen appears where you enter the functions you want to graph.
On the first line you have Y1= . After the equal sign enter 2[x] [X, theta,T] + 1. When finished press [F6: Draw] Your graph appears on the screen. If you see the axes, but no graph, press [Shift][V-Window] and press [F3:Std] then [SHIFT][QUIT] will take you back to the screen where you enter the functions to draw. There press [F6:Draw].

Hope it helps.

Hello,
No the calculator cannot convert decimal values into excat values.
Hope it helps.

You need to pick a type of distribution, and you can of course use the local radius for the center of mass or Cho as well. sx is probably in the alpha or alternate key functions, unless you want sy or course, or need to translate sy back into the variable it produced your distribution from.

You can fine the appropriate manual here:

Hello,
Use the key [x, theta, T] below the [Alpha] key, or use [ALPHA] [+] (x)
Hope it helps.

In it's back, there is a small hole-reset key. prick it with your pencil.
