I love that but it's missing 2 leaves

[–] 7eter@feddit.org 20 points 1 week ago* (last edited 1 week ago)

I got two more leaves for you πŸ₯¦

$$\left(1+\sin(\theta)\right) \left(1+\frac{9}{10}\sin(9\theta)\right) \left(1+\frac{1}{10}\sin(-27\theta)\right) \left(\frac{9}{10}+\frac{1}{10}\cos(200\theta)\right)$$

The number of leaves depends on the age of the plant. There are ones with one and three leaves as well. However I've never seen a leaf with a bud in the middle like on the left.

I like how you have all those random-ass coefficients and then there's just 1+sinΞΈ chilling there.

[–] 7eter@feddit.org 5 points 1 week ago

It's basically the length of the leaves. Wonderful how this can be described so simply!

It's possible to draw anything with a math function?

[–] fossilesque@mander.xyz 5 points 1 week ago* (last edited 1 week ago)

You could draw a representation of anything with a math function, yes. Have fun calculating anything complex though.

With polar coordinates and Fourier transforms, you can draw the outlines of tons of figures. But you can't go back. Imagine that you can go with your pen around the center in only one direction, but any distance from the center.

[–] Fleur_@lemm.ee 2 points 1 week ago

Short answer yes

But it actually depends on what you mean by draw

A web search tells me the ΞΈ (lower-case theta) is used to represent an angle. Do you just fill in 0Β° – 359.9Β° one after another to draw that curve?

[–] Sphks@lemmy.dbzer0.com 5 points 1 week ago* (last edited 1 week ago) (1 children)

Yes. https://en.m.wikipedia.org/wiki/Polar_coordinate_system

Since this curve is cyclical, you can do it [-infinity ; +infinity] and it's the same curve again and again.

Thanks. πŸ™‚
