Re: Graphing calculator help
The cord that comes with the TI-83 Plus is a unit-to-unit link cable. It allows you to share data from one TI-83 (or other compatible TI calculator) to another. If you have the optional TI-GRAPH LINK adapter cable and the appropriate software it can also be connected to a PC.
For more info, here is the link to the manual. Chapter 19 discusses it in great detail.
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
The service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones). click here to download the app (for users in the US for now) and get all the help you need. Good luck!

First you must use a graphing calculator.
Most graphing calculators graph functions, i.e. relations of the form y=f(x).
Some graphing calculators are able to graph equations (not necessarily functions). On one of these calculators your draw the vertical line x=-3, then you shade to the left of the point x=-3. That gives you the real line from infinity up to but not including x=-3.
Generally, people do not need calculators to find the solutions to inequalities in just one variable.
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.
While it may have many of the same functions as a graphing calculator. It cannot produce a graph on the screen. This is required for most classes. It is not considered a graphing calculator, and you will most likely have to buy a new one.
The casio FX-300Ms calculator cannot do graphs. To tell you how to use a graphing calculator TO DRAW GRAPHS we need to know the exact brand and model number of the calculator.
Most graphing calculators basically function the same way.
You select the graph type (function, polar,parametric, sequence, 3D, wire mesh, slope field, etc.)
You enter the algebraic form of the function you want to draw.
You press a button or menu to GRAPH
The graph is drawn.
If you want to see a particular part of the graph, you use a ZOOM function, or you enter values for the WINDOW dimensions.
Most graphing calculators have a TRACE function that allow you to follow the curve you have drawn to read off values of coordinate points.
You can also use the calculator to find zeros roots) of functions, calculate derivatives at some chosen points or calculate the area "under the curve", find the minimum and maximum of a function.
In addition to its graphing capabilities, a graphing calculator can be used as a scientific calculator. Sometimes it can also do statistical and financial calculations, matrices, list manipulations, operations on complex numbers, text editing,, creating programs etc.
Sorry, but you cannot calculate limits of functions with this calculator. It does not have a Computer `Algebra System (CAS). For that you need a graphing calculator with CAS: Casio ClassPad 300, 300PLUS, 330, HP 48 GII, HP49 G/ G+, HP 50G, TI-NSPIRE CAS, TI89 Titanium, TI 92/92PLUS, TI Voyage 200 PLT. It is still a very good scientific (non graphing) calculator However, you can calculate numerical derivatives, and numerical integrals, solve linear and non-linear equations.
Even though this post does meet your expectations, do not let that prevent you from rating it.
This error show up when you are graphing out of the plot menu. If you are not graphing data points from list menu, you need to turn the plots off. In the y= screen, you will see the words plot 1, plot 2, etc across the top of the screen. If one of the plots is highlighted (black box over the words), you need to turn it off. This can be done by arrowing up and highlighting the box and pressing enter. When you arrow back down, the plot should be off and you will be able to enter an equation in the y= lines and graph.
If you are graphing from the plot menu, this error lets you know that one of the lists you are graphing is longer than the other.
Another way to fix the problem is to reset the calculator by pressing 2nd button then plus sign then 7 then 1 then 2. This will reset the calculator however if you are graphing from lists, your data will be erased. Hope this helps.
The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:
In order to select additional graphs, the Transformation Graphing App
will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus
Family. Uninstalling the App does not erase it from the calculator, it
disables it from interfering with the normal graphing modes. Below are
the steps to successfully uninstall the App.
