  I love that but it’s missing 2 leaves

    try: $ (1+sin(θ)) (1+((9)/(10)) sin(9θ)) (1+((1)/(10)) sin(-11θ)) ((9)/(10)+(1)/(10) cos(200 θ)) $

    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.

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

    Yes. 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.

  It’s possible to draw everything with a math function?

    With polar coordinates and Fourier transforms, you can draw 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.

      … I think you can go back… but maybe I didn’t get your explanation

    You could draw a representation of anything with a math function, yes.

    Short answer yes

    But it actually depends on what you mean by draw
