How do you find the magnitude and phase of a complex number?
|a + bj| = √a2 + b2. The angle or phase or argument of the complex number a + bj is the angle, measured in radians, from the point 1 + 0j to a + bj, with counterclockwise denoting positive angle. The angle of a complex number c = a + bj is denoted c: c = arctanb/a.
How do you find the magnitude of a complex number?
Magnitude of Complex Number For a complex number z = x + jy, we define the magnitude, |z|, as follows: |z| = √x2 + y2. The magnitude can be thought of as the distance a complex number z lies from the origin of the complex plane.
How do you convert magnitude and phase to real and imaginary?
Conversion between the two notational forms involves simple trigonometry. To convert from polar to rectangular, find the real component by multiplying the polar magnitude by the cosine of the angle, and the imaginary component by multiplying the polar magnitude by the sine of the angle.
