Answered: TI-84 Plus gives me all answers in scientific notation?

Thu, 15 Jan 2026 13:05:27 +0000

This is a really common (and frustrating) TI-84 issue, especially during timed work, so you’re not alone. The calculator isn’t actually doing anything wrong — it’s just the display mode that’s causing the annoyance. Since your mode is set to ENG, the calculator will always show results in engineering notation for larger numbers (like 57.85×10³ instead of 57,850). To fix this and get normal numbers instantly: Quick fix: Press MODE Change ENG to NORMAL Keep FLOAT selected Press ENTER, then 2nd → MODE (QUIT) After this, 65 × 890 will display 57850 directly, no scientific notation, which is much faster for writing answers in exams. ENG mode is mainly useful for engineering classes, not everyday arithmetic, so NORMAL is the best option for timed assignments. If you want a clear step-by-step guide with screenshots and other TI-84 display tips, this page explains it really well: https://ti84calculator.us/ That should save you a lot of time (and irritation) during calculations

Answered: My TI-84 Plus calculator won't charge, it flashes OS error message

Mon, 28 Jul 2025 16:53:19 +0000

You didn't say what model of TI-84 you are using. The older TI-84 and TI-84 Plus is NOT rechargeable via the cable. The batteries supplied with the calculator are standard 1.5 volt AAA batteries. You can use rechargeable AAA batteries in the TI-84, but you'll need to take them out and recharge them in a compatible charger when they start to run down.

The newer TI-84 Plus CE is rechargeable via the supplied cable (USB-A to USB mini-B). If this is what you have, then it would help if you told us what error message you are getting from the OS.

Answered: how do i not reset the ram on a ti 84 plus when i switch the batteries?

Thu, 22 May 2025 17:39:25 +0000

It is possible to move your RAM memory to the ARCHIVE. You would do this by going to 2nd MEM, About, ALL. Press enter on all the programs you do not want deleted and a star should pop up next to them. This means all of them are archived and you can take out the batteries without risk.

Answered: TI-84 Plus CE Python only gives me answers in scientific notation

Wed, 12 Feb 2025 23:11:45 +0000

You are correct in that your mode should be one of "Normal", "Scientific" or "Engineering". Both Engineering and Scientific display answers with an exponent. According to the TI-84 manual, "Normal" mode uses up to 10 digits in the answer with the decimal point somewhere in the middle. However, there is this note:

Note: If you select Normal notation, but the answer cannot display in 10 digits (or the absolute value is less than .001), the TI-84 expresses the answer in scientific notation.

You will notice that the input "2574/2598960" gives the result "9.903961585E-4".

But "2574/259896" gives the result ".0099039616", which is what you expect.

The simple answer is to write the answer down and move the decimal point 4 digits to the left and leave off the exponent.

how do I download polynomial division: long and short onto my ti-84 plus calculator?

Sun, 07 Jul 2024 21:27:51 +0000

Answered: Y= x^2 -10x -53

Thu, 16 May 2024 21:06:36 +0000

I assume that you are trying to find the roots of "y = x^2 - 10x - 53".

The correct way to solve this one is to "complete the square".
But, on a TI-84 Plus, you can either graph it and see where it crosses the x axis by using the trace function, or you can use the "Apps" button for 9:PlySmlt2 to get to the Polynomial and Simultaneous Equation solver. Use the Polynomial Solver to get approximations of x1=13.83176 and x2=-3.831676.
An "exact" answer can be found by either completing the square, or buying a calculator that has a CAS (Computer Algebra System) built-in, like the TI-89 or one of the other advanced TI models.
To complete the square, start by setting the x expression equal to zero, and moving the constant term to the other side.
x^2 - 10x = 53
Next, take the x coefficient (-10 in this case), divide it by 2 and square the result to get 25. Add the 25 to both sides.
x^2 - 10x + 25 = 53 + 25
At this point you've got a perfect square on the left side. x^2 - 10x + 25 can be replaced by (x - 5)^2. On the right side, just add them together to get 78.
(x - 5)^2 = 78
Subtract 78 from both sides to get:
(x - 5)^2 - 78 = 0
You now have the difference of two squares on the left side (assuming you know the square root of 78) and can re-write as:
((x - 5) + sqrt(78)) ((x - 5) - sqrt(78)) = 0
This means the roots are:
x = 5 - sqrt(78) or x = 5 + sqrt(78)

Answered: how to factor polynomials

Sun, 21 Apr 2024 16:35:08 +0000

It's difficult to "factor" a polynomial on a TI-84. But you can find the "roots" of a polynomial via a couple of different methods.

1. Graph the polynomial. The points where it crosses the x-axis are the "real roots" of the polynomial. Let's graph y=x^2+x-6 and you see it cross the x-axis at x=2 and x=-3. That means two of the factors are (x-2) and (x+3).

2. If it's a newer TI-84 Plus, it will have an APP (under the 'APP' key) named "PlySmlt2" which includes a polynomial root finder. You can use that to find the roots, and turn those into factors.

Answered: Is there a Trig identity simplifier for the ti-84 plus?

Fri, 08 Mar 2024 00:22:28 +0000

You can find trig programs for a TI-84 Plus programs at this location:
https://ticalc.org/pub/83plus/basic/math/trigonometry/
Just do a search on that page for "ident" and it should show you everything that's available.

Note that I typed your identity into my TI-89 and it simplified it automatically. That's pretty much a function of any calculator with a CAS, which the TI-84 doesn't have.

Answered: program to create a slope field

Tue, 19 Dec 2023 23:03:49 +0000

When solving differential equations on a TI-89 calculator, you can specify that it graphs a slope field. This isn't available directly on a TI-83/84 calculator, but you can download a program to do it from:
https://ticalc.org/pub/83plus/basic/math/calculus
or
https://www.calculatorti.com/ti-programs/ti-83-plus-ti-84-plus
On either page, just use "Ctl-F" to find "slope". Many of those will be slope-field programs.

Answered: Will the Reimann Sum program work on TI-84 Plus CE?

Mon, 27 Nov 2023 20:56:30 +0000

The Riemann Sum program from this site should work on any TI-83, TI-83 Plus, TI-84, TI-84 Plus or TI-84 Plus CE calculator since all of them run the TI-Basic programming language. Even the new "python" models also run the original TI-Basic language in addition to the python language.
DISCLAIMER: I haven't tried this since I only own the TI-81, TI-82, TI-83, TI-84 Plus, TI-86 and TI-89 graphing calculators. But it should work.

Answered: 3x^4 – 5x^2 – 2 = 0

Mon, 20 Nov 2023 04:22:31 +0000

Hmm...This is a 4th order equation, and we only know how to solve 2nd order (quadratic) equations.

Maybe if we turned it into a quadratic by letting t = x^2 an replacing x^2 and x^4 in the original equation with t and t^2, repectively.
3x^4 -5x^2 - 2 = 0 becomes:
3t^2 -5t - 2 = 0 <--- that's a nice quadratic that we can solve using either completing the square or the quadratic formula:
(t -2)(t + 1/3) = 0 : Now substitute back for t = x^2 to get:
(x^2 - 2)(x^2 + 1/3) = 0 : now you can factor each of THOSE quadratics to get all 4 of the original factors of the original problem.

Answered: Even or odd function

Sun, 19 Nov 2023 22:05:00 +0000

In this case, the order of the polynomial tells you whether it is even or odd. The polynomial:
-8x^3 + 5x^2 - 2
is a 3rd order polynomial since the highest power that "x" is raised to is "3" and 3 is odd.

Answered: Find the slope of y intercept of the graph of the equation Y=3x-6

Sat, 18 Nov 2023 05:59:44 +0000

This is a trick question, right?
The equation is already in slope/y-intercept form of "y = mx + b" where m is the slope and b is the y-intercept. In this case, the slope is 3 and the y-intercept is -6.

Answered: can you port the Shrek movie to a calculator?

Sat, 18 Nov 2023 05:54:17 +0000

Brady,You asked "can you port the Shrek movie to a calculator?"
Answer: There would certainly be copyright restrictions on doing so. Also, the monochrome screen of the TI-84 Plus would produce a lousy picture, and sound would be equally bad given that there are no speakers on the TI-84 Plus calculator.

Answered: Divide 6x^2 -7x -2 by 2x -1

Sat, 18 Nov 2023 05:32:59 +0000

You can graph the answer directly by creating two graphs as:

Y1 = 6x^2 -7x - 2
Y2 = 2x - 1
deselect both of the above and graph the 3rd equation (the answer) as:
Y3 = Y1(N)/Y2(N)
At this point, graphing it doesn't tell you much. But you can use that graph to check the graph of the ACTUAL answer which can be found by simply doing the division to get a 4th equation of:
Y4 = 3x - 2 - 4/(2x-1)
You'll notice that the graphs of Y3 and Y4 match which proves that Y4 is the correct answer.

Help needed for the n-th derivative app I downloaded from calculatorti.com!

Thu, 14 Jul 2022 11:30:05 +0000

I installed the n-th derivative program on my TI-84 Plus CE calculator. But whenever I enter the function, it keeps showing me "d#=". Now I am assuming that this means the n-th degree derivative (e.g., first derivative or second derivative, etc.) of the function. But whenever I keep pressing "1" for the first derivative, the calculator gives me an error:

ERROR: ARGUMENT

Check the type and number of arguments. Press + on menu item for Catalog help.

I did try to put in zero (0) for "d#=" just out of curiosity. It just gave me the function (as I expected, because the zeroth derivative of a function is simply itself).

What I need help with is how do I navigate the issue with "d#=", so that for whatever value of n I enter, I get the nth derivative of f(x).

Any help on this issue would be appreciated. Thanks.
