# TI-83+ Graph: Batmanby chrisbouchard

I've been having fun with my TI-83+ graphing calculator lately, and I thought I'd put up some of the art graphs I've done.

This is a parametric graph. So for those of you who have the calc and would like to give it a try, the equations are as follows:
``` X1 = {1, -1}(2.5sin(.5T) + 4) Y1 = .7T + 2 X2 = {1, -1}(7sin(.5T) + 4) Y2 = 1.8T - 1.5π X3 = {1, -1}(cos(.5T) + 1) Y3 = 2sin(.5T) - .1T2 - 3 X4 = {1, -1}(.25T + 2) Y4 = .5T-1 + 2 X5 = .6T - .6π Y5 = .75sin(.5T) + 5 X6 = {1, -1}(1.4cos(.6T) - 3.4) Y6 = 1.7sin(.6T) - 3 ```

what does the "T" represent ?
Featured By Owner Jun 6, 2015  Hobbyist Digital Artist
In parametric equations, we give equation for both x and y independently in terms of another variable, usually called t (for time). To input it on your calculator, you can follow these instructions that I gave to another deviant.

Idk what i did wrong but i have no idea what to do D: I think i may have the settings wrong, i just got this thing today from my teacher

Hey i was trying to graph this but i couldnt find the "n" symbol on the calculator?

(see line Y2)

nevermind, my bad it was pi :/

gotta love sinusoidal
Featured By Owner May 11, 2012  Hobbyist Digital Artist
Eh, it has its ups and downs.
Featured By Owner May 14, 2012
it is kind of cool though it can go on for infinity
Featured By Owner May 14, 2012  Hobbyist Digital Artist
It's just a sine of the times...
Featured By Owner May 19, 2012
haha yes nice pun reminds me of IB math

does} and) make a difference??
cyberdjox Featured By Owner Jan 21, 2013
Yes, it does.
cyberdjox Featured By Owner Jan 21, 2013
It does make a difference x)
Featured By Owner Apr 28, 2012  Hobbyist Digital Artist
I'm not sure what you mean. They are both needed wherever they're used, and one can't be used in place of the other.

wahts the T?? and how do i put htat in?? im using ti 84+ se
Featured By Owner Apr 28, 2012  Hobbyist Digital Artist
Also, if the TI-84+ isn't too different from the TI-83+, you can try following these instructions I gave to someone else.
Featured By Owner Apr 28, 2012  Hobbyist Digital Artist
This graph was made using parametric equation. Instead of graphing Y as a function of X, both X and Y are graphed as independent functions of T. I'm not sure how to change into parametric mode on a TI-84, but that's what you have to do.

What's the little symbol thingy that looks like a table?
Featured By Owner Feb 25, 2012  Hobbyist Digital Artist
That's the Greek letter pi. If I recall correctly, it's a button on the calculator, but I don't know where mine is at the moment.
cyberdjox Featured By Owner Jan 21, 2013
on TI-83 Plus it's: [2nd] [^]

or one could just type in 3.14159 instead of Pi lol.

Math just got dynamic!

The head part of mine doesn't look the same... ;o;
Featured By Owner Dec 1, 2008  Hobbyist Digital Artist
Are you using a TI-83+?

Regardless, you might be able to turn off plots by pressing `[2nd]` + `[Y=]`, which should be `STAT PLOT`. In this menu, press `4:PlotsOff`, which will copy it to the display, then press `[ENTER]` to run that command.

I'm using a TI-84+ D:
Featured By Owner Nov 30, 2008
Why does it say invalid DIM when I try to graph it? D:
Featured By Owner Nov 30, 2008  Hobbyist Digital Artist
Make sure that all of the plots are turned off. Above where you enter the equations, if any of the plots is highlighted, select it and press `[ENTER]` to toggle it. Once they're all off, try graphing again.

How do you make your calculator graph x instead of y? o.o?
Featured By Owner Nov 27, 2008  Hobbyist Digital Artist
This graph was done in Parametric Mode. To switch to this mode, press the `[MODE]` button, and move down to the row with `Func Par Pol Seq`. Most likely `Func` is selected now; change it to `Par`. Now you will see `X`s and `Y`s when entering equations, and pressing `[X,T,θ,n]` will enter a `T`.

Thank you! ;3

1T2 what is that
Featured By Owner Sep 29, 2008  Hobbyist Digital Artist
I don't see a 1T2 in any of the equations, unless you mean the `.1T2` (and if so, you should have a look at FAQ #104: What HTML formatting can we use on deviantART? And what is the format for these codes?). My calculator has a `[x2]` button on it for squaring, but this could be rewritten as `.1T^2`.
Featured By Owner Sep 29, 2008
yeah thats what i ment
Featured By Owner Aug 14, 2008
That is awesome!
Featured By Owner Apr 23, 2008
i been trying to graph this one and its been kinda hard lol, first im new at this and i dunno the t min and max for it, well i put the t min at 0 but the max i dunno, i would really appreicate if anyone would help me, this looks really interesting.
Featured By Owner Apr 23, 2008  Hobbyist Digital Artist
I almost always graph in what I call Standard Square Zoom. First I set Standard Zoom (`[ZOOM]` -> `6:ZStandard`), then Square Zoom (`[ZOOM]` -> `5:ZSquare`). I believe this sets the Tmin=0 and Tmax=2π. I hope this helps, otherwise please ask more questions -- I'm probably just being dense.

Hey i tried to graph this and it didnt seem to work. What are your other settings? (xmin/max, ymin/max, any non-default modes?)
Featured By Owner Sep 15, 2012  Hobbyist Digital Artist
Unfortunately, I made this a while ago and haven't touched that calculator in years. As I recall, I didn't make any view changes beyond what I said in your parent comment. Of course, it was designed for the TI-83+. If you're using a newer calculator, the viewing area might be different.

In what way is it not working for you?
Featured By Owner Sep 18, 2012  Student Artisan Crafter
well all it does is make two giant vertical lines in my screen starting from the 0-line... think my window is too small?
Featured By Owner Apr 23, 2008
thanx man, fast reply lol appreciate it. i'll try it and see if i can make any good images, thanx a lot again.

Ok...that....is pure genious.
Featured By Owner Mar 23, 2006
na na na na na...and so on. Awesome graph man, i am going to try this one
Zyriox Featured By Owner Mar 22, 2006
omg ...mathematics
I never tried something like that,but it looks interesting.
I'd like to do stuff like that in our math lessons
Featured By Owner Mar 22, 2006  Hobbyist Digital Artist
That would indeed be a fun lesson. Thanks for the comment.
