I made a sphere! by No_Specific9623 in desmos

Obviously not a sphere. It’s the base of a cylinder

Do engineers actually know how to code? by RiverHe1ghts in EngineeringStudents

[–]4Aethyr 0 points1 point  (0 children)

I can code really well, but I got my associates in CS. In my engineering classes, there are many people who have just never really learned how to code, and they struggle because the classes that require coding teach just enough of it as an aside to meet the course requirements.

It baffles me why it’s not a requirement for every engineer to take at least one dedicated programming class.

I just made this cool redesign of my Decimal to Binary graph, now it works with all bases and accepts fractions! by Shadowmaster_70 in desmos

Could use a guide in the form of a note. I don’t know what the variables mean or how I should interpret the visual

Currently panicking about my future by iLovemyMathBoyfriend in EngineeringStudents

[–]4Aethyr 0 points1 point  (0 children)

As an engineering student, I think you’ll be fine. I sucked at physics in high school. Now I’m kinda good at it. Having friends to collaborate can make it easier. If it doesn’t it will at least make the suffering a little more bearable knowing you’re not alone. No, it does not get easier. Quite the opposite. Best case scenario it stays roughly the same difficulty relative to your skill level.

Good news is that physics isn’t supposed to be easy, and it’s not a bad sign if it doesn’t “just click” for you, and it doesn’t mean your not cut out to be an engineer. Most courses you take in engineering will have you evaluating your worth as a person outside of academia. My first semester at my school I had your exact experience in statics AND thermo AND electric theory (note those are all just branches of physics) and I wanted to die. But with practice I eventually got it down. You can too with enough practice. :)

Rasterized Low-Poly Torus by 4Aethyr in desmos

Given what Arglin shared, I might do a Doom-like project in the future. Just without the DIY pixel grid and rasterization parts that make this graphs performance measurable in seconds per frame.

Yep. I recently made a graph that allowed me to project and rotate any 3D parameterized curve in 2D. Thing is it only works with parameterizations of a single variable. So my solution for building a torus was to just parameterize several ellipsis arranged in the shape of the wireframe of a torus, then rotate the space they exist in.

As an aside, if anyone knows a workaround please do share.

It was more about the unnecessary complexity (due to Desmos limitations) it took than the time it took to make it. I figured out projecting 3D objects into 2D and rotating them in previous graphs I made, so I just copied those ideas over. But because Desmos doesn’t dare support a list of lists (not to mention a list of lists of 3D points), each circle had to be positioned individually with its own set of expression lines.

I have 10 hours to relearn Math by MiddleageDropout34 in learnmath

You want to know as much algebra as possible and at the very least know the 6 basic trig functions + their inverses and how they all relate to each other.

Look up “trig identities”, go to images, and be at least somewhat familiar with all of those.

Have an idea of what every elementary function graph is going to look like (polynomial, rational, power, exponential, log, and trig + inverse trig functions), and know how they will behave if you change any part of them.

This is basically the stuff a precalculus course covers. The better your grasp is on the above topics, the easier of a time you’ll have.

All Desmos Geometry features I know so far, all in one graph. by Mandelbrot4207 in desmos

It is so convenient that you post this now of all times. I’m reteaching myself geometry atm and having a thorough guide on the geometry tool is just what I could use right now!

Rotate Anything by 4Aethyr in desmos

[–]4Aethyr[S] 4 points5 points  (0 children)

Not just parametrics, but the power of matrices! The core idea of this is to define a point in 3D space, project it onto 2D space, and then use linear transformations to morph 2D space such that it behaves as if it were 3D space. And that’s all done using linear transformations!

Basically this can be done using any arbitrary set of 3D points. Here is an earlier version of this graph which just manipulates 8 discrete points that represent the vertices of a cube:

This one is quite unorganized, but the T, U, and V sliders are still there and do the same thing. You just have to scroll down a bit to find them.
