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

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.

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

Many thanks!

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.

Thank you so much.

Hello Kris, Pi/4 is 0.7854 thanks.

Many thanks! James.

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!

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