Math Equation Christmas Tree and Graph

[Imager]

I posted this link a couple years ago, but just in case you need to draw a Christmas Tree:

There are a lot of interesting variations posted, maybe PF could have our own contest!

Here's the link to the original thread:

That sounds like a great idea. Perhaps @Greg Bernhardt can comment on it.

I know the DESMOS Calculator has a creative art using equations section posted below:

where a student did a greeting card for Christmas:

Ok math and science brains, it's time to get creative and festive! Using LaTeX or on a graph can you build an amazing christmas tree or holiday/winter scene using math equations? DESMOS is a great tool to use. Post your equation set and photo and maybe you'll get gold membership!

x = ± 1/(y^(√y))

Makes a nice tree kinda shape

You should post a pic too.

Just for a start, could add a tree trunk to the bottom.

and some color too

I also got one!

The ski looks kind of weird.​

You can type: $|x| = \frac{1}{y^{\sqrt y}}$, that will make it one function.

Looks way more like a tree than post #6

Now this looks just like a tree.

The shape itself looks like a a Hershey’s kiss candy without the silver wrapper and pull tab.

But it looks really cool when colorized and stacked.

Next you could add some animation parameters to it to make the trees grow into place and snow appear.

Looks kind of like what I searched online.

Now we're getting closer, let's keep adding on to it!

It’s been a while since I last work on this.I know that it is 2019 now and Christmas had gone by.

I am going to make a similar graph on PF’s logo, but I am having some trouble on making the notches on the tilted ellipses for those “electrons” .What could be the possible factor to do that? Maybe using a circle function at that spot and eliminate the lines within?
