Complex number - Wikipedia

WebThe polar form of a complex number is: z = z (cos (θ) + i⋅sin (θ)) = z e iθ or z = r (cos (θ) + isin (θ)) = re iθ Here, z (or r) is known as the complex modulus θ is known as complex argument or phase . Тhe dashed circle above represents the complex modulus z of z and the angle θ represents its complex argument. WebA complex number is a number that can be expressed in the form a + bi, where a and b are real numbers and i is the imaginary unit, which is defined as the square root of -1. … WebAn argument of the complex number z = x + iy, denoted arg (z), is defined in two equivalent ways: Geometrically, in the complex plane, as the 2D polar angle from the positive real axis to the vector representing z. The numeric value is given by the angle in radians, and is positive if measured counterclockwise. Algebraically, as any real quantity child\u0027s recliner big lots
