I love that but it's missing 2 leaves

[–] 7eter@feddit.org 36 points 3 weeks ago* (last edited 3 weeks 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.

It's a mutation, happens rarely. I've had a couple of plants do it in the 5 or so years I've been growing.

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

[–] 7eter@feddit.org 8 points 3 weeks ago

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

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 7 points 3 weeks ago* (last edited 3 weeks 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™‚

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

[–] fossilesque@mander.xyz 5 points 3 weeks ago* (last edited 3 weeks ago)

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

[–] Sphks@lemmy.dbzer0.com 4 points 3 weeks ago* (last edited 3 weeks ago) (1 children)

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 1 points 3 weeks ago

Short answer yes

But it actually depends on what you mean by draw
