Thank you very much....For myself,the most fruitful part was that of the gear,,transforming linear motion to sinusoidle motion,along with the moving circle example.
At 1:31 you have both equations on the screen, the explaination gets a bit muddled. Do you mean to write this: "f(x) = A * cos(2*PI/Lambda) * x" ? Or, do you mean to write this: "f(x) = A * cos(2*PI/Lambda * x)" ? I only mention because after you write present the formula you don't specifically mention the variable "x" or the variable "t" any more. You focus on 2*PI/Lambda and 2*PI/Theta. I only mention because all of the explainations for graphic sine and cosine functions, everyone on the internet seems to have a slightly different version way to explain the formula. And that's very confusing to young students.

FANTASTIC! MINDBLOWING! AND UNBELIEVABLE!!!!!
Thank you so much! I am only in algebra 1 and I am doing a presentation including the wave equation and this video made everything clear!

You always save my life with your videos! Thanks a bunch!
Nice video, but I really needed the sine part
Helpful especially in terms of better understanding the uncertainty principle
Thank you for this lesson.
You hear that Mr Andersen? That is the sound of inevitability.
Matrix?

Excellent!! My compliments!
keep running and making an educated clan.

your "f(x) = A * cos(2*PI/Lambda * x)" is the correct one. i am saying based the simulation formula he used.
Teacher: class we will be studying geometry today.

Amazing job
Super helpful ♥
Thank you
What do you think about morgue with his sinusoidal waves
You should make t-shirts

imagine all the best teachers from youtube teaching in one school/ college.
in school that may not be that effective what you see here.
perfect for a student like me
Thank u so much dear
I don't understand this. what do I need to know before watching this.
I’m somewhat confused. If lambda is the length of a ciclo and 2pi is also the length of a ciclo, then what is their deference?
Thanks 🙏
2pi has a fixed value always i.e. 2x180=360 degrees. Lambda is wavelength that unit is length measurements.
that was helpful
thanks a lot
what about sin?
Thanks :)
u should do ap physics 2
good
Always~
That AP test was way fucking easyer than I thought.
Teacher pay should be linked to exam scores. This guy would be homeless. QED.
Good it to hard subject
no
