# Neat things to do with your graphic calculator!

I’ve been using a graphing calculator for like 4 years, and I’ve learned how to graph really neat stuff; and how to program your calculator to graph shapes for you with only the vertices of the points.

Try putting this into your calculator:

y1=cos(1x)+5
y2=cos(2x)+4
y3=cos(3x)+3
y4=cos(3.5x)+2.5
y5=1.5
y6=sin(1x)-2
y7=sin(1x)-4
y8=sin(1x)-6
y9=sin(1x)-8
y0=-9.5
Default=Circle(10,10,4)
Axes=Off
ZStandard=On

This makes a nice landscape of some mountains, a lake, and a sun!

Or try putting this in instead:

y1=5x^-1
y2=4x^-1
y3=3x^-1
y4=2x^-1
y5=x^-1
y6=-5x^-1
y7=-4x^-1
y8=-3x^-1
y9=-2x^-1
y0=-x^-1
Default=
Axes=On/Off
ZStandard=On

This makes a nice diamond picture!

Or perhaps something to do with making shapes:

There you have a nice triangle program!

Do you know of any neat stuffs?

Edit; fixed.

Anything using Sin, Cosin, or Tangent will turn out crazy, especially if they’re taken out to exponents.

Something seems wrong with my triangle program. >:( I will fix it.

My most recent works involved programs for some special cases of graphic making. One of them had a graphic calculator, I enjoyed drawing on it too.

All TI 83s need to burn.

Why? I use a Texas Instruments graphic calculator. Probably TU something or other.

1. They’re known as Graphing, not graphic calculators.
2. Does anybody really care? Those things have a complete alphabet on them. You can spell BOOBS without 80085

Don’t know Xel, lines are pretty cool.

You can also draw dicks, but don’t let the teacher see.

Pretty much all through high school, I just sat in the back and played “drug warz” on my TI-83 PLUS. Yeah, I sprung for the plus, since I’m worth it.

Dagnabit! In my day we drew our graphs out with a pencil and paper and that’s the way we liked it!

I play Doom, and the Elder Scrolls on mine.

Ninten:cool:

We spell funny words on our calculators. ;-; Maths= boring.

On my scientific calculator, I got some of the alphabet. A, B, C, D, E, F, G, H, M, P, X, Y, and Z. So I end up writing B00B5.

I use my old TI-85 at work even though they gave us scientific calculators when we were hired; I like the larger display with the graphing calculator. I even have some cute penguin stickers on it.

I frequently played drugwar on my calculator in high school and in the beginning of college, but I deleted it to have space for several games (like Tetris, some mining game, and a couple of others). I kinda miss how my physics teacher would get pissed when someone in the front row was playing drugwar and not even pretending to pay attention, ha ha.

I remember drugwars. That game was fun.

I used a TI84 plus… and I couldnt figure it out :(.

I like to code fun little cracktro-style demos on mine. Spinning cubes, texture fillers, starfields, stupid shit like that. I’ve got a TI-83+, and have had it since 7th grade, and i love the thing to death. If you’re someone who enjoys expressing yourself through code, these little computers fucking rock. They’re the equivalant to a simple pen and paper to an artist, you can just whip it out, anytime, anywhere, and code a cool little demo or something.

The coolest thing i’ve done with mine is make a real-time clock that can count up and down, allows input so you can say “Tell me when this period is over”, and can continue running even when the calc goes into “powersave” mode (!) I’ve also got a cool little 3D game, where you are a cube, and move around avoiding other cubes. The entire thing is in perspective, so when you turn, all the 3D objects rotate with you.

Some of the 3D stuff i’ve done is pretty neat too, though really simple. If i have one gripe about the machines, its that they can do as much as any computer, and yet TI locks you out of the cool functions. (thats why “programs” you make with the machine are so limited, but the “applications” they give you are so robust).

But like i said, the simple nature is quite fun to fuck around with. If i had the link cable or whatever, i’d link up and dump some of my programs here. D:

I can barely do basic math on mine.
I haven’t the slightest idea how to use the bitch.

I hate my graphing calculator with a vengence, but mostly cause i have trouble figuring out with no instruction type book.

I miss borrowing ti-89’s for my math class. They were so easy to use and they made limits and integrals so simple.
