What is Phasor and Sinor diagramme? What are they plotted agsinst? And how to interpret them?
I have sample pic from my textbook.

A phasor diagram is a graphical representation of the amplitude and phase relationship between two or more sinusoidal signals. Its purpose is to visually illustrate the phase and amplitude relationships between these signals.
To construct a phasor diagram, you first need to determine the amplitude and phase of each sinusoidal signal. Then, you draw a horizontal line to represent the reference signal (usually the largest amplitude signal). Finally, you draw a vector for each signal, with the length representing the amplitude and the angle representing the phase, and place the vectors on the horizontal line.
A sinusoidal signal is a type of periodic signal that follows a sine or cosine function. It is important in phasor diagrams because many electrical signals, such as AC currents and voltages, are sinusoidal in nature. Representing these signals as sinusoidal phasors allows for easier analysis and understanding of their behavior.
A phasor diagram represents the amplitude and phase relationship between sinusoidal signals, while a Sinor diagram represents the amplitude and phase relationship between non-sinusoidal signals. Sinor diagrams are used for signals that are composed of multiple sinusoidal components.
Phasor diagrams are commonly used in the analysis of electrical circuits, particularly those involving AC currents and voltages. They are also used in fields such as signal processing and telecommunications to analyze and understand sinusoidal signals. Additionally, phasor diagrams are helpful in designing and troubleshooting electrical systems.
