Question about Casio FX-9750GPlus Calculator

Ad

Hello,

I am sorry but I will have to assume that you know how to enter the data.

Once you enter your data [MENU][STAT], press [F1:Graph], select Gph1,
Gph2, or Gph3. Once the graph of the experimental data is drawn, you
will have access to the diverse regression models. Your choices are
[X:Linear] [Med-Med], [Quadratic :X^2] [Cubic;X^3] [Quartic: X^2].
Press [F6] to scroll right to access the others: [Logarithmic:LOG],
[Exponential :EXP], [Power :Pwr] and [Sinusoidal: Sin]

After you select a model and press [EXE], the screen displays the
equation and its various coefficients. On that same screen, you have a
menu option [F6:Draw]. If you select it, the regression curve will be
drawn on the same screen as your statistical graph. This allows you to
judge if the fit is good. If it is not, you have the option to choose
another model.

The other option [F5:Copy] allows you to save the regression equation in the Y1, Y2, etc. variables.

Hope it helps.

To solve this with a ti-84 press [math] and select solve from the menu. This will open the equation solver. Type in your equation

(Note: you may need to put it in the form with 0=, So the equation would be 0 = 2c + 6 +7c - 8 ). Then press

enter or arrow down button.

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

--> TVM

Viola. The initials TVM stand for Time-Value-Money; it's a widely used tool throughout financial mathematics. If you are looking to deal with annuities, bonds, present value equations, future value equations, or even certain stocks then you will want to use the TVM app within your TI-84.

When you go into that menu screen you will see about 10 input lines; and despite how you're being taught you'd be best off using only five (from a mathematical & conceptual standpoint). The backbone of the TVM is the time-zero equation of value. So, all you want to be touching is the N, I/Y, PV, PMT, and FV keys.

Background on TVM:

N = Number of intervals

I/Y = Effective Interest Rate Per Interval (5% is .05 but the computer wants it entered as 5.0)

PV = The Present Value

PMT = Recurring Payment (either deposit or withdrawal)

FV = Future Value

There are like 3 other inputs that I encourage you to ignore (in exchange for learning exactly what's going on within this application).

NOTE: You MUST make your effective interest term match your number of intervals. For example, an annuity with monthly payments for 5 years with a monthly effective interest rate of 2% would need an N value of 60 (which is 12 months per year times 5 years for a total of 60 months).

There's more that could be said, but I think this should help you find the PV of an annuity.

You need to change the mode from Math Print to Classic Mode to get the multiple line display. Press Mode to open the correct menu. Use the up/down arrows to make sure that an item in the first line is highlighted (MathPrint or Classic). Use the left/right arrows to select Classic. Press Enter. If you see a line labeled Save, use the down arrow to highlight the line and press Enter again.

This is briefly shown in the manual. See page 9 (page 16 of the PDF) for the menu that applies. The section is labeled Setting the Clock. The rest of the details on changing modes is on page 15 (page 22 of the PDF). Texas Instruments has the manual for the TI-84 Plus Silver Edition in their support section. Start here: https://education.ti.com/en/guidebook/search?active=guidebooks . The direct link to the manual is https://education.ti.com/download/en/ed-tech/C4D11EB6D86B47D19CD768E54A967441/6CC4C5AED5004F808892046AD33D4A35/TI84Plus_guidebook_EN.pdf .

I hope this helps.

The Ti83/84PLUS are a lot more advanced than the TI-30XA because thaeu can graphs, statistics, calculus etc. But they lack a key for the % function, and a key for the fraction manipulation, the angle unit conversions (deg, radians, et grads) and they are a lot more expensive than the TI30XA.

Before your daughter finishes high school, you will eventually have to buy her a graphing calculator but right now a TI83/84Plus calculator seems like overkill. Besides some teachers may not let students have graphing calculators during exams.

Honestly I suggest you buy the TI-30XA Solar version. There are some new nifty calculators manufactured by Casio (Casio FX-115ES, FX-991ES, FX-300ES), Sharp (El-506W, 516W ). The beautiful thing about these new kinds of calculators is that you can configure them to use the Textbook display: equations and expressions can be entered as they would appear in textbooks. The Casios are called Natural Display and the Sharps are know as WriteView models.

In fairness to Texas Instruments, they too have calculators that incorporate that display format but I do not know the exact model numbers (maybe TI34XII multiview).

Ok, try these two things and you should be just fine.

1.) Check your range for your graph. It is possible that the range you are using isnt large enough to show the curve. Also try using Z-fit vs Z-st. These are options that your calculator will give you once the equation is graphed.

2.) Place a parenthesis around the 2x, make sure that you and the calculator are both using the same order of operations. This move mill ensure that the calculator will multiply the variable, x, by two and then do the exponential.

This should do it!

Happy Graphing!

Hello,

Please do not dislike your math teacher,**for your own sake**: You will not learn much from someone whom you dislike. Now Relax.

All the applications that were preloaded in your calculator are available to download freely from http://education.ti.com Use the tab Download--> Apps and software. Then select software for the TI83/TI84 Family. While you are at the site download the TI Connect, if yoy do not have it already. The link follows.

http://education.ti.com/educationportal/sites/US/productDetail/us_ti_connect.html You can also download the latest OS there.

Install TI connect on your computer and run it to open the main Window.Then connect you calculator to a USB port and, in the TIConnect main window Click the TIDeviceInfo icon. Software will try to retrieve the info. If it does your calculator is ready to communicate with the computer.

If it tells you Device Not found , Click communication settings in same pop up window where it said Not found, and Select Device, Select Cable (USB or TIsilver cable), Select Port (USB1) and Click OK..

If you are lucky and it works, you can reinstall the OS, which can be downloaded from education.ti.com. You drag and drop the OS on the TIconnect main window. Calculator must of couse be connected to computer. To install an application already downloaded to you computer, drag it to the main window of TI Connect and drop it. Keep installing, the appilcations you want.

If you have problem with TIconnect, use the calc-to-calc cable to transfer the Apps on a working calculator. Yous should be on Receive mode [2nd][Link] --->>Receive. (When both calculators are ready hit enter.) The other calculator, you guessed exactly right, must be on Send [2nd][Link][SEND][C:Apps]. A list of Apps appears. Scroll down the list. If you want to transmit un app you press [ENTER] when the arrow reaches its line. Once an app is selected , a small square appears on the left. After the selection, Hit transmit. I suggest you transfer Apps, one after the other. Avoid selecting them all and send them all at one go.

Hope it helps

Yes, the Ti nspire not only functions as a ti83 but, also operate w/ nice advance math software that any teacher would envey. It comes with the ti83 keypad plus software and great instructions to help the instructor at all levels of math learning. I don't know any better and it is a beautiful plan that ti has set up.
