Understanding Angular velocity, Omega t (wt), Sine, Unit Circle and Phase difference

That moment at 3:19 “omega tf?” is giving me life. Hahaha

Thank you deeply for this amazing lesson! It made me see things differently and understand them better. Cheers!

Hi Dillinger, it's great to hear comments like this. It took months to make and it's worth it when people take the time to comment, especially when it helps people understand. My teachers many years ago skipped so much, so it was a challenge to understand, back in the 1990s. Take care and feel free to share. See also Electronics4engineers channel. Thanks again, James.

This video should be sent to Khan Academy so that the world can benefit

[@phiwondaba8558]

Excellent video thank you so much!!!

[@titusnelson9499]

Nice review. Thanks.

[@E4E]

Many thanks!

[@ahmdkalef2252]

great representation of phase shift concept

[@Maths4Engineering]

Many thanks! James.

[@d.g.s.7572]

Excellent.. One of the best explanation. Thank you very much Sir🙏🙏🙏

[@E4E]

Thanks for taking the time to comment, it's very kind of you and I'm really pleased that it helped! If you need any other videos making, I'd welcome some inspiration! Cheers. James.

Excellent presentation Sir. Thank you very much.

[@ariebudiansyah8590]

you forgot to mention about formula of phase to radian from sin 30 degree = n/6 which is coming from 2.phi divided by 360 degree = (2n/360 degree)

[@E4E]

Hi I didn't forget, I put the relevant info but thanks for being vigilant!

[@bipanjitkaur9054]

Perfect mathematicians

[@E4E]

Thank you so much.

[@sayedhassanphysics8491]

❤ Nice 👍

[@aswathkumar2519]

Thank you 🙏

[@E4E]

You're very welcome, Aswath. Feel free to see my Electronics4Engineers channel too. All the best, I appreciate the kind comment. James.

I'm working on it.

6:34 isn’t the frequency of the shown graph 1/(2pi). Because the graph shown has a period equal to 2pi.

[@E4E]

Hi, at the time you mentioned, the circuit has done one cycle in 2pi radians. Remember, the x axis here is in radians, not seconds. A one Hz signal will always spin through 2pi radians or 360 degrees in one second. I hope this helps!

thank you, sir

Pi over 4 is 0.72 or is my calculator wrong?

[@E4E]

Hello Kris, Pi/4 is 0.7854 thanks.
