SOURCE: graphing

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.

  • Press [APPS] key
  • Select Transfrm from the menu
  • Press 1:Uninstall

SOURCE: My calculator will only graph one graph at a time.

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)
Hope this helps!

SOURCE: how can I graph two equations at once?

Hello,
Once you enter an equation the corresponding equal sign is highlighted by default. Before you draw the 2 graphs, move the cursor to Y3 or Y4 and verify that the = signs for Y1 and Y2 remain highlighted. If one is not highlighted, move the cursor on it and press ENTER.
If you still have problem, press [2nd][STATPLOTS][4: PlotsOff] [ENTER]
Command PlotsOff echoes on main screen. Press [ENTER], screen displays Done.
If all else fails, just reset the RAM by pressing [2nd][MEM][7:Reset][1:All RAM][2:Reset], press [CLEAR] to clear the message.
You shouild make it a habit to clear the RAM every time you start a new type of problem.

Hope it helps.

SOURCE: I cant graph more than one equation at a time.

A) Before drawing function Y1=f(X), R1=F(Theta), (X1=f(T0, Y1=f(T))
you should turn the statistical plots OFF.
To turn statistical plots off

  1. Press [2nd][Y=] to open the (STAT PLOT) menu.
  2. Select [4:PlotsOff] and
  3. Press [ENTER].
  4. Calculator displays Done
  5. Restart your graphs.
  6. Adjust the window dimensions if necessary or use the ZOOM function to have all graphs displayed.

B) If you cannot draw more than one function

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.

  1. Press the [Apps] key.
  2. Scroll down or up to reach the Transfmapplication.
  3. Select it and press [ENTER].
  4. If that application was running you will see a new screen that tells you some thing like
    • Transfrm App
    • 1:Uninstall
    • 2:Continue

    Press1:Uninstall.
    Graphing functionalities will revert to the native OS

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

To uninstall it, do as for the Transfm and select the option that will unload it from memory.
  1. Press [Apps]
  2. Select [ : Inequalz]
  3. Screen displays INEQUAL RUNNING
  • [1:Continue]
  • [2:Quit Inequal]
  • 3:About]
Press [2:Quit Inequal]

Why would your pulse rate be over 100


There are many reasons for a high pulse rate. Your pulse rate is the same as your heart rate. A common cause is anxiety. A heart rate over 100 is called sinus tachycardia . Sometimes bearing down as if you are having a BM will "reset" the heart. to normal sinus. It is related to vagal nerve stimulus. An obvious reason for increased heart rate would be physical exertion/exercise. Some medications may also cause an increase in heart rate. Sinus medications have been known to cause this. Too much caffeine will also increase the pulse.
There is also a condition called atrial fibrillation or A-fib. If your heart/pulse rate is not beating in a regular rhythm, it may be a-fib and must be evaluated. In any case, if your pulse rate is consistantly above 100/min you should see a cardiologist to determine the cause.

THE HEART BEAT MONITOR STAYS ON


follow this instruction and fix it. God bless you
If the chest pulse monitor does not display a reading, make sure you have it positioned properly. It should be against your skin, under your clothing, with the sensor right side up and the logo facing forward. If you still do not get a response, move it slightly higher or slightly lower on your chest. Position yourself properly too. When walking on the treadmill, stay in the middle of the walking belt. The heart monitor works on normal heart rhythms; it will not detect your heart rate if you have an abnormal rhythm

What is Automated external defibrillator?


Wikipedia says: An automated external defibrillator (AED) is a portable electronic device that automatically diagnoses the potentially life threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in a patient,[1] and is able to treat them through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm.
With simple audio and visual commands, AEDs are designed to be simple to use for the layman, and the use of AEDs is taught in many first aid, first responder, and basic life support (BLS) level cardiopulmonary resuscitation (CPR) classes.[2]

How to graph linear equation in two variables


I am not quite sure what you are asking...

(1) if asking for graphing y= -2/3x+2, then press [diamond] [F1: Y=] type in .2/3x +2, see graph by [diamond][graph]

(2) if asking for graphing y= -2/3x+a, where a=3x, then first archive a=3x in Home screen by [home], type 3x [sto] a, then go back to y= menu, and type -2/3x+a in Y1

(3) if asking for graphing an equation that is dependent on 2 variables at the same time, use x-y-z axis (aka, change mode to graphing 3-D by [mode]graph [5:3D]) then enter desired equation in y= menu using Z function in terms of x and y aka z(x,y)= ...)
