If you know the coefficients, you could use a quadratic solver since you know the two equations are quadratic. Basically, you just think of it as Y1-Y2=0.

However, if you don't want to input coefficients and just use the Y= vars directly, then it gets a bit complicated. Still doable though! The first thing you need to do is evaluate Y2-Y1 at three points. For convenience, we'll do -1, 0, and 1. From these three points, we can construct the coefficients:

Evaluate the three points:

Y1(⁻1)-Y2(⁻1→A
Y1(0)-Y2(0→B
Y1(1)-Y2(1→C

Interpolate to get the coefficients:

.5(C-A→D
2(Ans+A-B→A

(The quadratic equation is AX²/2+DX+B)

Now we just do our standard quadratic solver, but we'll add some safety checks:

If A:Then
D²-2AB
If Ans<0
Ans+0i
√(Ans→B
Disp (D-B)/A,(D+B)/A
Else
If D=0:Then
If B=0:Then
Disp "INTERCEPTS EVERYWHERE
Else
Disp "INTERCEPTS NOWHERE
End
Else
Disp ⁻B/D
End
End

NOTE: This only works if Y1 and Y2 are quadratic (i.e., ax²+bx+c, but a and/or b are allowed to be 0)

There may be easier ways on the newer calcs, I'm not sure, but this should work either way :)

There's a TI-Basic Developer Discord??

Nevermind, I'm in now

I found a link to the Discord, but I don't have permission to chat in it- could someone help with that?

They're knot all that too confusing, it takes time getting used to with what all the buttons do, menus, commands, etc

If you're wanting it simple and sweet, I'd try using https://ticalc.link/.

Most likely you use Google Chrome, so if you have a mini-USB cable and a file to send, that website is pretty easy to use without the installation of software of any kind

That is a crash, it happens occasionally.

can i get a step-by-step way on how to upload files to my ti-84 plus? bc search is still not working at this moment.

no actually I am used to it but I just think its confusing. lol i'm only a middle schooler.

Re: Ello there by ImSorryWhatImSorryWhat, 01 Jun 2022 20:56

I am currently a middle schooler that is using the most confusing calculator.

Ello there by ImSorryWhatImSorryWhat, 01 Jun 2022 20:49

but the thing that confused me was that it randomly wiped the ram, while I wasn't doing anything.

I keep getting syntax error even though I put everything in correctly.

If the mines are randomly generated, is there ANY way to know where they are? Otherwise, the game is completely luck.

I wanted the difficulties to do more than change the points you earn per cycle.
Since the program doesn't actually increase fall speed, I changed it to having higher difficulties use more spikes, by replacing 5 with 4+S. Since S=1 for easy, S=2 for normal, and S=3 for hard, this wasn't too difficult.
However, when I did this, the range for spike spawning also increased. This caused spikes to spawn farther to the right than the player could move. Is there a way to make it so the spikes spawn in the player's range?
Another error this would solve is that sometimes, spikes will spawn to the left of the players range, also rendering them pointless.
Also, is there a way to change the player's range?

There is unfortunately nothing you can do. Unless you manually created a backup at some point (which it sounds like you didn't), whatever data you had is gone.


The solution to a complex problem is often a simple answer.

I am trying to find a way to find the intercepts between a quadratic graph and a linear graph using TI-Basic. Lets say, for example, Y1=X^2 and Y2=3. Obviously, there are two intercepts for these two graphs. How do I find both intercepts using a program in TI-Basic? If clarification is needed, I am using a TI-84 Plus.

Please help me with this, it would really mean a lot to me because I hand-typed the programs' code.

What is this game?

Thanks so much, this helped out massively when I accidentally cleared all my apps. I could not just give up all those programs by 'upgrading' to 5.6, so (very lightly) scouring the internet I went, and here I ended up.

I also loaded this onto a calculator I had reset to sell, just so they'd have the option to download games or not.

Thanks again
