The polar form of a complex number expresses a number in terms of an angle θ and its distance from the origin r. Given a complex number in rectangular form expressed as z = x + yi, we use the same conversion formulas as we do to write the number in trigonometric form: x = rcosθ y = rsinθ r = √x2 + y2.
In this section, we will focus on the mechanics of working with complex numbers: translation of complex numbers from polar form to rectangular form and vice versa, interpretation of complex numbers in the scheme of applications, and application of De Moivre’s Theorem.
Polar form of complex numbers are represented in the cartesian plane using modulus and argument formula. Learn how to convert rectangular form to polar form, with examples at BYJU’S.
The abbreviated polar form of a complex number is z = rcis θ, where r = √ (x 2 + y 2) and θ = tan -1 (y/x). The components of polar form of a complex number are: r - It signifies absolute value or represents the modulus of the complex number. Angle θ - It is called the argument of the complex number.
This section covers the polar form of complex numbers, explaining how to represent complex numbers using magnitude and angle. It details the conversion between rectangular and polar forms, and the …
Polar Form for a Complex Number. The complex number z = a + bi can be written in the polar form. z = r(cosθ + isinθ) where r = √a2 + b2 and θ is defined by. a = rcosθ, b = rsinθ, 0 ≤ θ ≤ 2π. The angle θ is called the argument of the complex number, and r is its length, or modulus.
In this section, we will focus on the mechanics of working with complex numbers: translation of complex numbers from polar form to rectangular form and vice versa, interpretation of complex numbers in the scheme of applications, and application of De Moivre’s Theorem.

So we can write the polar form of a complex number as: `x + yj = r(cos θ + j\ sin θ)` r is the absolute value (or modulus) of the complex number. θ is the argument of the complex number.
