Ok, this is both for b&w and color calculators. Just go into the graphics program from the main menu (top right on 9850) and plot this in:

r1=1
r2=1.1*
r3=5
r4=4.9*
r5=1.2* (orange)
r6=1.3*(orange)
r7=4.8* (orange)
r8=4.7* (orange)
r9=1.4
r10=1.5*
r11=4.6
r12=4.5*
y13=X-0.2 (green)
y14=X+0.2 (green)
y15=-X+0.2 (green)
y16=-X-0.2 (green)
y17=X*
y18=-X*

NB: coordinates marked * are for colo(u)r calculators only. If yours is b&w, just skip to the next one. The colo(u)rs listed are for calculators who has it, if it doesn't contain a star as well you just plot it into the b&w. Allso take notice that some are r= and some are y=

Looks nice... pretty colors... Takes a while to draw on the 9850. On the 9860 it took only a couple of seconds.

Although the sniper scope could be made simpler, but this for fun, ok...........

r12 = r(q) = 4*sin(q/5), 0 < q < 5p , -6.8 < x < 6.8 , -3.5 < y < 4.5,
xt13 = x(t) = cos(t/5+p) , yt13 = y(t) = sin(t/5+ p) ? 1,

xt14 = x(t) = cos(t)/3 + 1.6 , yt14 = y(t) = sin(t)/3 + 1.6,

xt15 = x(t) = cos(t)/3 - 1.6, yt15 = y(t) = sin(t)/3 + 1.6,

xt16 = x(t) = cos(t/5-p/4) + 2.8 , yt16 = y(t) = sin(t/5-p/4) + 2.8,

xt17 = x(t) = cos(t/5+p/4) - 2.8, yt17 = y(t) = sin(t/5+p/4) + 2.8.

Awesome.. LOL!!!! pretty bear!

[kucalc]

Wow! That teddy bear is cool! Hope people would post more fun graphics!

[kucalc]

Here are some graphics that might be interesting:

Draw a flower:

r1=Asin Btheta

Example:
r1=3sin 3theta

Manipulating A modifies the size, B manipulates number of petals.

Draw some partial spirals:

r1=sqrt(theta)
r2=-sqrt(theta)

Try 1sin 100theta
This makes for one smashed up spiral! use auto-zoom to find it...
1sin 50theta - a spiral supernova! again auto-zoom, this is tiny...

[TyYann]

What about some DYNAmic graph ?

With your calc in Radian, your V-Win in trig, I got this on my 9860 :

Y1=sin AX

Var: A
Start 1260
End 1280
Step 1

Enjoy !

(my favorite is 1270)

Actually it's even more beautyful on a 9850

[TyYann]

Yes, with the same parameters :
Set in radian
V-window :
xmin = -6.8
xmax = 6.8
ymin -3.5
ymax 4.5
T min
0
T max
5{pi}

But it's really slow...

Is there a way to delete all functions at once? It takes a while if I delte one by one.

[kucalc]

Yes, there is a way. On a fx-9860, go to the Main Menu and go to Memory and select it. Press F1 for Main Memory, then scroll down until Y=Data and press F1 to select it. Now press F6. That should delete all of those functions.
