Electrical Engineering ⇒ Topic : Exponential form
Exponential form. According to Euler's equation :
ejθ = cos θ + j sin θ
Similarly, e-jθ = cos θ - j sin θ
The trigonometrical form of representing a phasor V is V = V (cos θ ± j sin θ). Therefore, the phasor V may be represented in the exponential form as
V = V e±jθ
Here V is the magnitude (or modulus) of the phasor and ± θ (or argument) is the phase angle of the phasor from the reference axis (i. e. OX-axis).
