thanks in advance

Yea both are same, but if i put an =x text, how does it become a bernerd graph WHILE THEY'RE THE EXACT SAME!?!?!?

For the function sin(b(ln(x²+y²)))=0 for b€R the geometrical ratio lambda of this function(r_{n+1}/r_{n})=e^{π/2b}.

Wowie Zowie!!!​

Hey guys! I think this is pretty neat.

While reverse engineering Desmos for this project, I ended up getting a pretty good understanding of how it works internally. I've always wanted to define my own "built-in" JavaScript functions in Desmos, and since I also wanted to build my first browser extension, I decided to give it a shot - and I actually managed to do it.

The first time you open the extension, you'll see a few built-in functions like isprime, primefactors, lambertw, and more (see the screenshots). I picked functions that I thought could be somehow useful to people. You can edit, disable, or delete any of them.

You can also create your own functions using the Function Builder Dashboard (see Picture 3). Just enter the body of the function you want to define, reload Desmos, and it'll be available instantly.

It works with both Desmos and Desmodder.

I didn't upload it to the Chrome Web Store because it costs $5 to publish an extension there, so you'll have to install it from GitHub instead (it's really not that difficult, you can find a guide in the GitHub README).

If you want to see it in action, here's a Fourier series drawer that uses some of the custom functions:

Note: As I said, I'm still very new to this kind of stuff. I tried to make the extension as robust and user-friendly as possible, but Desmos' internal code changes constantly, so I can't guarantee it'll still work a few weeks from now. It'll probably need ongoing maintenance, and I don't know if I'll have enough time to keep up with it in the future.

If anyone more experienced than me wants to help out, I'd really appreciate it (just message me). I also had an AI help clean up and organize the code, so hopefully it's not too painful to work with.
