AC Signals - Radians and Degrees? Why do we use both?

Click For Summary
The discussion revolves around the use of radians per second for angular frequency and degrees for phase shift in electrical engineering. Participants highlight that while Hertz (Hz) is commonly used for frequency in practical applications, radians per second simplifies calculations involving oscillations and calculus. The preference for radians is attributed to its mathematical convenience, particularly in equations like V=V0cos(ωt - kx). There is a consensus that while radians are useful for theoretical work, Hz remains the preferred unit for general communication and practical measurements. Overall, the conversation emphasizes the importance of clarity in unit usage to avoid confusion in engineering contexts.

Was there anything wrong or nor clear about this?

No - everything clear. As I have mentioned there was a confusiuon on my side regarding "dimension" and "unit".
(See my post#22: ...it is not dimensionless. It has the unit rad).
