ROSE

------------



A curve which has the shape of a petal flower. Curve was named

'Rhodonea' by the Italian mathematician Guido Grandi, between 1723 and 1728 because it resembles a rose.



The polar equation of the rose is":



r = Alfa * sin * (n * Theta) [spin]

r = Alfa * cos * (n * Theta) [anti-spin]



If N is odd, the rose is N-petalled. If N is even, the rose is N-petalled.

If N is irrational, then there are an infinite number of petals.



N = 2 - Full anti-spin flower.

N = 3 Trifolium(Paquerette de mlibe)

N = 1/2 Half flower.

N = 1/3 Lock-out.

N = 1/5 Snake



Quote:



"If is N = R/S a rational number, then the curve closes at a polar angle

of Theta = PI * S * P ,where P = 1 if R * S is odd and P = 2, if R*S is

even."



Did anyone understand tha last?



PEDAL CURVE

-------------------------



I found that there are flowers divaded into families depending on

origin of the flower, the center.



Trammel(Astroid base) - Full 4 anti-spin flower, with center.

Trimmel(Deltoid base) - Full 3 anti-spin flower, with center.

Hyperbola(Ellipse base) - Circle, with focus(!).

Hypocycloid(Epicycliod base) - Rose(!).

Point(Line base) - Point.

NEGATIVE PEDAL CURVE

-----------------------------------------



I found, that there is relation between trammel and four fioled

anti-spin. That Trammel is it's, negative pair(!).



That circle negative is elliypse or hyperbola.

SUPERSPIN

---------------------



It is the ellypse.

coupled that with the fact that we know you already know the answer ("a concept you all KNOW I already understand."), it gets tricky to see exactly how simply we need to spell it out for you whilst not being condescending.

I'd never accuse anybody trying to teach me something of being condescending. That was not my accusation.

I believe that y'all knew exactly where my lack of understanding was. I also think that on the internet giving clues can be really frustrating and (more importantly) not educational.

I always thing that being 'purposely vague' can be extremely frustrating and harmful in education. Of course, when learning CONCEPTS you don't always want to just hand someone all the answers BUT I think that some have tendancies to frustrate me when I'm confused by being "purposely vague" which I think is different than helpful.

If it takes more time and effort to be purposely vague by giving clues and such than by just spelling out the answer then I don't see the point.

Unless it's to mess with me, in which case it's funny. But I don't think that was the case.

Also throw in 3 biases:
1) I'm a teacher who constantly battles with the best and worst ways to educate.
2) My entire poi persona in New York has been teaching others for nothing in return. Nobody out here has ever taught me much of anything, making it extremely frustrating it when I'm out there and ask what I'm doing wrong with my btb weave and folks said stuff like "think about circles" or "you need to get stoned" rather than the real answer which was "move your right arm further left".
3) My lack of ability to get help and inspiration pretty much made me give up poi.

All of which are 100% my fault/responsibility but are my biases.

Posted:Well, function of flower was written to give a theoretical

aproach when thinking about flower. It prooves, that spin

and anti-spin have diffrent timing, but not in case of the

rhythm, but the initial position.



Than 'goofy' flower, can looks like sinus and cosinus time

line, where the point of the curve represent actual di-

stance form 'center'.



It can be shown that snake is a curve with N = 1/5,

I think one could differe if the move, moves the

whole sinus curve or only amplify.

Thank you Coleman, Glass, NYC to bright light the whole

theory with interesting notes.



ayt,

Posted:nyc - hug

i honestly didn't mean to be obfuscatory (blimey! that's a clever word for first thing on a monday morning!).

from my side of things, as we did indeed already know you understood the concept - as such i thought all you would need would be a list of the ways in which r could vary with over time other than by changing the string length on the fly (shoulder-elbow-wrist circles, tangles and isolation).

nobody to teach you in nyc?
just move to london next march... biggrin

Posted:You come visit me in New York and then IF you leave you'll at least understand why it'll take a bit more than poi to get me out.

hug

But I'll soon have family in London so that should give me some street cred and more reasons to visit. wink

Posted:There's essentially one thing many forget you can do with flowers. That beeing you can spin them and wrap them ( spiral wraps ) around the hand.

I find that if they go into the spiral when they are furthest in front of you they will go out and reverse around the time they are furthest back of you. So you can keep both arms doing spirals. ubbrollsmile

Posted:It is truth, that you can wrap Poi around body part

to get spiral effect, but it is fundamental techni-

que and here you'll find theoretical flowe overview

rather than aplication.



This thread closes relation between spin and anti-

spin, becasuse there are few "low level "anti-spins

undescribed yet.



0 anti-spin

1 anti-spin



The 2 anti-spin is trammel. I can help you, spin

has two borders, giant(long arm) and full izolation.
