7:23 why are we putting delta theta as 2pi? Coz as soon as the oscillator comes back to its original position at time T, the displacement is 0 and not 2pi? I'd be extremely thankful to anyone who can explain🙏
We're not setting the displacement equal to 2pi, we're setting the inside (phase) of the cos function equal to 2pi. Then take cos of it and multiply by amplitude to get the position x (or "displacement")
4:28 *please help!* How can we put *t= 2pi* when t is *time* and 2pi radians is the *displacement/angle travelled* ? How are we equating these different physical quantities together?
That was great! I love the way you broke down the function and explained how/why it works. This is the clearest explanation I have seen. Thank you!
What an explanation struggling to understand from last 5 years. Thanks a lot.
Now I can feel it what is harmonic in terms of cos and sin
You are really awesome the best physics teacher i have
This is a true life saver.
Amazing video! Thank you for sharing !!!
seriously man beautiful explanation
That was great... really helped....thank you so much!
thank you very much, your video is very beneficial
Keep up the good work thanks
good explanation, thanks

icecream We’re plugging in t=2pi seconds (i.e. t=6.28 seconds) not 2pi radians.
What program are you using to show this? I want to use it for teaching my math class at the middle school, it would be perfect! Thank you!!
My knowledge is 98% internet and 2% school
Hhmmmm I don't understand most of this.......... Looks like I've got to learn everything after math 2😅😅😅
