Wow!! I will probably remember this forever now. The answer to the question should be same size (because of same Amplitude) and same speed (because of the same amount of time it takes to complete one oscillation).
The second, (blue wheel) is CLEARLY spinning twice as fast as the red wheel and it is the same size. So you are wrong, and the author of the question just made t10 = 20 and t20 = 40 in the blue to make it a trick question.
@@andrewfetterolf7042 The question is visually tricked. For first one the motion recorded slow in video, while for second one motion recorded in video faster, that's why it looks that way, but looking at X and Y axis things are different. And for the same reason, X axis in second one is made bigger.
Succinct and effective video. A sign wave explained with a very good analogy! Would you please also share some real life problems this waveform helps us understand and perhaps solve...
Yesterday I decided to learn how the whole thing works (because the SIN seems to be used a lot in things like animation, video games calculations, etc.) and the more I understand it, the more I'm in awe how someone could even come up with the whole thing. Trigonometry is really ingenious, the more you look into it.
Thanks for Indian Sanskrit contribution “Ardhya” we still use the latter word in our daily social communication for example “give me half of the fruit or any item by saying “give me Ardhya”
Square waves are ultimately a superposition of multiple sine waves, with a pattern of increasing frequency called harmonics, and decreasing amplitude as frequency increases. Look up the Fourier series of a square wave, and Fourier transform that generates them.
Good mention. You should do a video on square waves. I watched some embedded electronics videos where the guy would throw them on that wave machine to explain inverters & transformers IIRC and there were times where the waves were square shaped instead of a nice sloping rounded line
This I so understandable even if its 2 years ago it's still understandable !!! thank you I'm going to use this example in my maths expedition and make a real model thank you!!! This is so helpful to me!!!
How come this did not come in my recommendations till now... Such a beautiful video... Thanks a lot guys... This channel should have more subscribers... But I see that you have only 11 videos...I think you guys should make more videos... You have a great explanation technique... Thanks a lot and wish you the best
London Eye - one day i'll be there! So the sine wave just tell's me the height of the person on the giant wheel and cosine the horizontal displacement .. right?
Yes Ronnie, agreed. Very interesting that the original word was simply chord of a circle. I'm guessing mathematicians didn't have any intent to create confusion but over time (and geographical distance) the name changed ...
They are both going at the same speed, however the red wheel only completes one revolution while the blue wheel completes two revolutions, in double time than it took for the red one. They are also the same size. Please correct me if I'm wrong.
They are the same size Ferris wheel, but the blue one is faster! (I hope) Either way, hats off for this exaplanation. It was well worth the RUclips digging through a few other videos to find this one. This is going to help me so much. Thank you, thank you, thank you!
Hi Shane, thanks for the appreciation! Take another look at the horizontal (x) axis of both plots and you'll realize that they are rotating at the same speed!
Since there is no increase in strecth, means both the peak values are same, the red and blue Giant Wheels have same size. If we observe the both figures, both the giant wheels complete 1 cycle in 20 mins so they have same time period.
Hi Adarsh, Thanks. So if you draw parallel chords in a circle (and then just look at half chords), you'll notice that their lengths from smallest to largest (when its actually the diameter or passes through the center) and back to smallest is simply the amplitude of the Sine wave varying as it starts from time 0 ... Hope this helps!
As per my understanding I am thinking of the vertical motion of the Red square moving through time in the horizontal direction and then tracking the movement of the square that will produce a sine wave
I'm trying to understand. I believed that the sine-function resulted in values on the vertical axis (Y-axis)?. And therefore the "red square" (plotted sin(x) - values?) should not rotate but go up and down the y-axis as the wheel rotate. (In the same manner as the red dot movement looks like from the side (1. dim)? And then this up-down movement on the y-axis is streched out in time to get the sine-curve as a function of time? But I may be on deep (wavy..) water here....
amazing, just one thing: the name of the wave has to do with the concept sine from geometry; I think not explaining that and only explaining the origin of the word will confuse some. Otherwise a fantastic fantastic video. Thanks a lot!
Wave or Helix, a look at the Electromagnetic Wave The electromagnetic wave has both an electric field and a magnetic field. These are perpendicular to each other. The illustrations online for the electromagnetic spectrum show a range of wavelengths from radio to gamma waves. But the illustrations show waves, never a helix. So which are they? See my diagram. The electric wave is a vertical wave in red, and the magnetic wave is a horizontal wave in blue. They are perpendicular to each other. Next see any of the numerous animated RUclips videos on sine waves and cosine waves. Mapping a helix or moving circle or spiral with a sine wave and a cosine wave, shows exactly the same thing as my drawing. That seems to suggest that electromagnetic waves are not waves but helixes!!! This exactly fits a sine and cosine wave mapped as a helix , spiral, or moving circle. This seems so obvious, yet I've never seen an electromagnetic wave represented as a helix or spiral. Has anyone else?
Tom, once we make a video on light, you'll have a much better understanding and maybe get some answers to your curiosity. If you make a vector that adds magnetic and electric field, it behaves like a "helix". Please wait for our video on Light. Your curiosity and questioning is right on track! That's what the world needs to get answers to understanding nature!
@@RoseUniversity Thanks, Responses have led me to circular polarization, which in turn led to a study on how microwaves affect electrons, which suggests this may connect up with constructive and destructive interference in charged particles, which connects up electrons and positrons...
Very good explanation. Thanks. Can you please explain graphs of exponential functions and how can we explain related rates of change through graphs. dy/dt = dy/dx × dx/dt If you explain these I will be grateful and many students will be benefited with your work.
Awesome! breaking it down to just a simple circular motion helps to understand it a lot better than textbook equations 😀 Thanks!
You're very welcome!

Can u explain square wave also ...?
