Graphing stuff on the 83+ and higher

[psychicmon]

:confused: Is there any cool little graphs that you enter in the y= button? Or any program that you type in basic. for staff: please dont send this topic to basic. Just a plea. My friend gave me a y= form and he said the result was supposed to do something with utah. All it did was create a wierd picture. :confused:

I'm not quite sure I understand your English, but if you mean, what are some functions that produce cool results, I would try a simple google search for "cool graphing functions"

Here is one for the polar graphing mode from the second result...

My Zoom Factors were off. Use this instead:

ZTrig
47/96[font="times new roman"]π→Xmax
‾Ans→Xmin
[s]1→Ymin[/s] 1→Ymax
‾1→Ymin

[simplethinker]

Awesome!!!!!! Where did you come up with this? I am crying now.
Do these graphs have names?

[Weregoose]

Parametric equations.

Also, be sure to set Tmin=0, Tmax=2[font="times new roman"]π

[simplethinker]

I was wondering if any of the individual graphs generated have specific names, like a rose curve or whatever (I never payed attention to my math teacher when talking about graph names)
All of the T parameters (min,max,step) were set to what you said

"for staff: please dont send this topic to basic. Just a plea."

Well, maybe not, but I think this topic would be more at home in "Math and Science." ;)

"I was wondering if any of the individual graphs generated have specific names?"

Unfortunately, not every named curve is beautiful, and not every beautiful curve is named. ;)

A lot of nice stuff can be found at http://www.2dcurves.com/ and http://www.mathcurve.com/ (in French, but it does have nice animations).

Offhand, I have these nice curves:

x=(2+.5sin(AT))cos(t+sin(BT)/C)
y=(2+.5sin(AT))sin(t+sin(BT)/C)

due to N. Starr. These following parameter values look good:

{A,B,C}={8,16,4}
{A,B,C}={6,18,18}

and you might find nicer ones by playing (fooling?) around with the values. Be sure to use a small enough value of TStep. ;)

I kinda like this one:
Y1={1,2,3,4,5}sin(X

[psychicmon]

] y1= 2x
] y2= -2x
[ y3= x\2
[ y4= -x\2
[ is the triangle up or the \ thing pressed twice
] is the triangle down or the \ thing pressed thrice.
for those people who dont know what that means :confused: , it means three times.

Yes he does; that's pretty interesting.

And Goose? Your's took forever to type in (and to figure out that funky superscript symbol was [2nd][Apps][3]) but it was definitely worth it.

Since I have no creativity in coming up with ones, I'll point out a few by Super Speler.

[Weregoose]

The brick pattern can be done with Y1=Ymax and Y2=Y3=Ymin (all shaded above), but a more realistic pattern is achieved by:

For(A,2,4,2
Shade(Ymin,Ymax,Xmin,Xmax,A,A
End

As for another graph...

Y1={1,‾1}√(1+{1,‾1}√((1-X)³(X+1
Y2=‾Y1

(Smile!)

[psychicmon]

weregoose. I dont get the post you ut up third or whatever. I just get a circle thats shaded. Big whoup. Now here's something cool
Y1={1,2,3,4,5,6,7,8,9,10,-1,-2,-3,-4,-5,-6,-7,-8,-9,-10} sin(x
Y2= -Y1 cos( x
its big but cool
and weregoose, do you mind puting up a better version of your graphing program? i dont get it. Are you supposed to have the " in front of a few line? :confused: and the person who posted after me first is a party pooper

[Weregoose]

[psychicmon]

first of all

[DarkerLine]

47/96 Pi -> Xmax
-Ans -> Xmin
1 -> Ymax
-1 -> Ymin

[JoostinOnline]

Sometimes people just copy code out of programs like GraphLink, and symbols will be displayed incorrectly. Unless ? is in quotes (a string) then you know it is supposed to be something else. When posting code, there are two ways to get around this. You can either make substitutions like -> for store (as done by Darkerline), or you can copy symbols from someones signature. The second way takes longer, and is not used as often, but it makes the code look nicer.

[DarkerLine]

Well in this case psychicmon just seems to have unicode troubles.
