Trig is so underrated and so is geometry. I actually like them more than algebra xD EDIT: just checked back on Mar 7th. So many likes! Thanks! I just want to say I made this comment as a one-off from a 16 hour workday.
How is it underrated? Literally every STEM field uses it CONSTANTLY, same thing about geometry these are famous topics with endless real life applications, and they relate to real life easily I mean geometry and trig literally by the name and what it is, are about measuring land and triangles. It's so easy to relate to real life it's hardly a topic people question
@@spoperty4940This was a comment obviously made by a child, take it easy. Let them have fun. I agree with you, I’m taking a STEM major right now and it’s definitely essential.
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. Very cool.
Trigonometry is important in electronics engineering as well, because you use the sin function to calculate and compare AC currents on the oscilloscope. Also in mechanical engineering to calculate forces and things like that(even though it's mostly the Pythagorean theorem).
@Dain Baptist not really, trigonometry is more the sin, cos and tan of angles formed on arcs of a circumference. It's somewhat related but you don't use it to calculate the aforementioned.
@OrthaluminoxPythagorean Theorem is important but it’s not the heart of Trigonometry. The majority of trig is based of right triangles but with different laws and calculations, you can answer more difficult questions involving Sine, Cosine, Tangent, ArcTan(Cot), ArcSine(Csc), ArcCos(Sec).
Really great project. I don't really know how but it would be cool to keep the motion of the balls but that can cross each other in the middle of the arcs. Using the phazes to make the balls avoid each other.
Try making every single one of the arks having a sin wave slower that the ark before, and start them in sync. After some time it will become the wave, then the 90 degree thing, then the 180 degree thing. You basically make a polymeter out of these arks!
@@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. Trig stuff is everywhere.
fridge the roof need cuts, and angles. So you can use trig on that part. For the structure and cuts. Also, If a room is square, then the two diagonal corner to corner measures will be the same.
Math was always so difficult for me as a kid because I'm a visual learner. Being able to SEE what the numbers and equations actually mean in the real world is sooooo helpful!
That looks really great. You should try what the first 3 or 4 component waves of a Fourier transformed triangular or a trapezoid waveform look like when they are played out next to each other.
I’m a fan of anyone fighting the “math taught in school is useless” narrative. Sucks if you were unable to realize the applications and power of mathematics.
Trig is intertwined in a lot of other disciplines. Physics, Calculus, Engineering, Statics, every math is useful and creates a base for each other like Geometry is a base for Trigonometry and they both make bases in Calculus.
The last set before all of them together: UTTERLY SATISFYING in every way. EASILY one of your best pieces yet…and it’s an amazingly helpful demonstration of waves!
Another great way to view this is top down at the machine. If you can imagine the ball moving in time (4d space) or forward on the sine graph, you get the ball moving along that graphed line. Just hope this helps some people view it differently.
Could you show what happens with 120 degrees apart? Might be interesting because 3 phase power is 120 degrees between phases, and I don’t fully understand it and this might help visualize it 😂
Trig is very useful. Used it to calculate line of sight thickness of sloped armor. Used it to determine range of the target. Used it for stabilizing a gun turret.
Very nice visual demonstration of phase :) You could have also drawn graphs representing the positions of the balls to show the 90° phase change between the driving force and the oscillator associated with forced harmonic motion. You can see this in the clips where the arcs are 90° out of phase with each other, when the ball in the front is at its maximum height, the arc behind it is also at its maximum angle.
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.
All of those movements are pretty cool in their own way. What would make them more interesting would be to randomly rotate through each of these pre-programed movements morphing between one movement to the other
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

It gets really cool when you can get it to smoothly transition between all of them

True! Next video :)
So are u saying the balls actually represent the wave?
Thanks brother 🙂
Damn that's a great video for explaining phase on a basic level, good job man
Thank you!
I appreciate the extra time to watch at the end after explaining it so I can marvel , great touch
The 90° one is my personal favorite :D
Same.
yes, it looks confusing and insane. I want something like that.
90° is the laziest angle to still not be pointless. 😌
90° one feels just right to me
I love the last version of the smooth wave motion 🤩🤩

You won’t be using this in your daily pleb life of course. Engineere and scientists use this.

Smooth wave was nice but I really liked that juggling motion
The second looks like multiple entity's in one spot in a game.
