Title: Online 3D Function Visualizer + GeoGebra 3D Calculator
Post by: WAS on December 16, 2019, 10:37:19 PM
I wanted to check some formulas and I was having issues getting a sense of "depth" from the one N-drju shared, and I came across this. It's a little more basic in that you need to write the formula in a basic input field, but at the same time, a lot of formula examples are in plain text and use the same syntax. I found this after I found GeoGebra which is also really nice, but I find it a little slower to work with.

Yep, I found this one too. It's a good resource to visualize vectors, but I find Desmos to be more comprehensive and fun to use.

more comprehensive how? inherently you lack depth as a key variable as it's 2D, so you're having to do some interpretation yourself. GeoGebra is technically the same thing, but in 3D, which when working in 3D space is the best visual representation.

More comprehensive, because first you need to understand how 2D algebra works in order to get how it translates into 3D space.

Desmos does just that - I can enter some base arguments an then change them according to will, assigning them to various trigonometric functions. Even with the little knowledge I have about these problems, I can still mostly understand why an equation looks the way it does. And I can also tell why the equation looks different when I change a function or an argument.

Here, however, I haven't got the slightest clue of what's going on in the 3D space. Exchanging just one number alters the entire terrain portion in ways I could not even anticipate. I find it impossible to explain with the knowledge I currently have... Why, I can't even tell if these are vectors or maybe some other shit.

I'm not saying it's useless. Just saying this is probably the "next tier" resource, which I don't feel comfortable with just yet.

I think you have may be misunderstanding the basics... 2D space, especially when dealing with 3D space, is not more "comprehensive". It's the opposite. Comprehensive is something complete, including all elements/aspects of that therein. The fact you can't comprehend the 3D version of the same thing in 2D (which still is a 3D representation) is puzzling. This is the true result you're after, so if it's not comprehend-able, but the 2D is, how could you ever achieve an end-goal if that goal "looks different" (when that IS it) or hard to understand?

Additionally, 2D algebra, is it's own thing/goal. Hence the categorized realms, 1D, 2D, 3D, 4D.

I think this is more just a personal opinion thing, rather than comprehensive representations.
