Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

I can only graph one thing. I also having a problem shading for inequalities

Ad

The Trasnfrm application is usually the culprit. Go to APPS and choose the Transfrm app, then in the menu that comes up, choose Uninstall.

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.

The solution set of a linear inequality in two variables (x,y) is one half of the Cartesian plane. The half-plane may or may not contain the boundary line defined by the = sign. Thus it is expected that the calculator shades the relevant half-plane. If you are dealing with nonlinear inequalities the calculator shades inside or outside the curve.

When drawing multiple inequalities the Casio offers you the possibility to shade the regions where ALL conditions (ALL inequalities) are simultaneously satisfied. The other option is OR.

**If you are not interested in the shading do not draw inequalities, draw equations (with =)**.

Press APPS. Scroll up or down to reach Inequalz and press ENTER. The inequalz application will know control function graphing. Open the Y= editor to enter at least two inequalities . Use the tabs at the bottom to type in the relational operators. You will have to press [ALPHA] followed by [F1], or [F2], etc

Press the GRAPH function key (F5) to draw the graphs. You get the two regions superposed (original shading).

Press [ALPHA][F1 or F2] to activate the [SHADES] tab. This open up the following screen.

On this screen you can choose the type of shading 1: Intersection of the two regions ( the part of the plane that satisfies both inequalities, 2 the union of the two regions or 3 the original shading (as compared to choice 2). Selecting option 1:intersection gives you the following screen.

If you press the [ALPHA][F5] keys you have the HELP ? screen below.

If you press the [ALPHA] [F3] keys you get a Point of Interest (You should consult the manual for the Inequalz application for more details.

By pressing the TRACE button (not ALPHA F4) and the left or right arrows you you can follow the graph of one of the functions. You jump to the other functions by pressing the Up or Down arrows.

To get the manual for Inequalz go to the education.ti.com and download it.

You don't need an app. Just press the Y= button and enter the inequality as if you're entering another function to be graphed. Then press left-arrow repeatedly to move to the diagonal line at the left end of the display. Press ENTER repeatedly to cycle through the different graph styles. If the inequality is of the form "y less than" or "y less than or equal to", select the shaded triangle below the line. If the inequality is of the form "y greater than" or "y greater than or equal to", select the shaded triangle above the line.

you should turn the statistical plots OFF.

Usually as soon as you start entering an expression in the Y= editor screen, the = sign is highlighted to ensure the drawing of a function. However, if you have previously used the Transfm application to draw dynamic graphs, it takes over the graphing functionalities from the native OS and you can only draw a single graph.

The reason is that dynamic graphing needs one or two parameters that can be changed during the graphing process and the graph redrawn with a new value of a parameter, and you end up with a family of curves differing one from the other by the values of one parameters. But since the calculator has space for 10 graphs at most, only one function can be highlighted.

To make a long story short, you must uninstall the Transfrm application from memory. The procedure will not erase it, just kick it out of memory.

Another potential culprit is the Inequalz App. You recognize that Inequalz is runnibg if the [ Y=] editor screen shows tabs at the bottom

Do you want to change from graphing functions to inequalities or the opposite? A complete sentence would help.

I am going to assume that you want to graph y=f(x) functions, but when you opened the Y= editor, you found unusual symbols.

If the is the case, then you must have run the Inequalz Application. It stays in memory and takes over the graphing from the native OS. Inequalz must be unloaded from memory to return control to the native OS.

Here is how to do it.

Basically, the "arrow" key to the left of Y1 becomes >|, and then the = sign is highlighted for the equation that is being graphed. I have heard that there is an app for this, but which one...?
