And you thought trigonometry was pointless…
•••
It’s because highschool math curriculums fail to give context to the principles they’re treaching. Even in the first couple years of engineering school, I found that I had to search for context on my own. But it made all the difference. It’s crazy how much easier math and science is to learn when you can actually see it in action.
•••
There are many different ways to get this motion using the servo motor configuration I have here. After a few days of searching for answers, I stumbled upon this, which gives a very elegant solution.

​@@zafar5059 in our world there are three types of waves mechanical (sound waves), electromagnetic waves (light, Uv, gama, infrared red, etc.) which propogate in the way balls do so these rolling balls help you understand motion and difference between waves when these is a phase difference, it also helps you understand interference when two waves comply and form another wave with a larger amplitude, they also help in the understanding of simple harmonic motion, osscilations, movement of electrons( because electrons are like waves too in quantum mechanics) and many more places, it helps in understanding of otherwise such complex phenomenons in an easy way by sin and cos components

I just love the synchronicity of the balls doing the fluid wave movement. In effect what you're doing is translating a *Rotational Wave* (alternating rotating approx. 15° left/15° right, on the pivot point of a "U" shaped section) on a vertical Y/Z (width/height) plane, to a *Flat Wave* (amplitude left/amplitude right) on a horizontal XY (depth/width) plane.

@@jenkathefridge3933 you can use it to measure circles, triangles and any shape you can make from those. Its is used to measure the size of height of structures. Sine waves are used in AC electrical, so I can use it to find out phase angle and is used to express those functions in general. We see that voltage in resistors and voltage in indicators are 90 degrees out of phase, but if their drops are different we don't get a 45 degree angle, we use trig functions to find the total impedance, pythagorean theorem is used here, and the phase angle is the angle of the resulting triangle.

Now multiply this by a thousand and you've got a Reuben Margolin sculpture. But really, I like this a lot. It reminds me of that physics demonstration where a set of progressively longer pendulums start in sync, then go out of phase, and eventually sync back up again. I wonder if you couldn't take the "juggling" a step further and have the cradles tilt way far to one side then snap back, tossing the ball from one side to the other. On its own, it would just be kinda cool, but if you got them to sync up so as to create a rolling cascade of aerial balls, it would be pretty radical. Like surfing through a wave tunnel, only pinker and more ballsy.

I think how the things rotate using those servos for each one of the 5 is that they split up the sine wave in lots of small computable pieces and get the tangent slope on each of the points on the curve and rotate more if the curve is angled to face vertical the fastest and no rotation if it’s flat or horizontal, then just invert it or add a Boolean that does that if it goes below the middle line which is basically just making it so that if the tangent line faces down you should go the other way and then just add some offset to each of overlapping sine wave from each of the n number of those ball rolling rotating arms with the perboloid curves in them and set the different of each or the amount that they are spread apart to make a smoother or more oppositional sort-of effect. Opposite movement for every other one and perfect sync are opposites to each other.

Interesting to see this represented mechanically. The principle of the last example is used in 3-phase 12-pulse inverters (particularly for large variable speed drives). A pseudo 6-phase supply is created using different transformer winding configurations to produce a phase differential (star/delta or extended-star). You end up with much smaller troughs between the peaks of each phase resulting in a smoother DC output with less ripple when rectified.

Fun fact, this sine wave rotation is part of the formulas that allow us to power home far away from power substations! Three phase power uses this in conjunction alongside AC power sources, where each power source is rotated 120 degrees away from each other and given a voltage a certain ratio above the target amount. The average voltage of these three power sources as they reach highs and lows in their voltages results is standard voltage numbers, typically upwards of 1000 volts for long distance power supply! To sum it up you called my favorite graphing function useless and I needed to show it off
