Derivative of a phasor
Multiplication by a constant (scalar) Multiplication of the phasor $${\displaystyle Ae^{i\theta }e^{i\omega t}}$$ by a complex constant, $${\displaystyle Be^{i\phi }}$$, produces another phasor. That means its only effect is to change the amplitude and phase of the underlying sinusoid: In electronics, $${\displaystyle … See more In physics and engineering, a phasor (a portmanteau of phase vector ) is a complex number representing a sinusoidal function whose amplitude (A), angular frequency (ω), and initial phase (θ) are time-invariant.
