  • θ = the argument (or angle) of the complex number
  • a = the real part of the complex number
  • b = the imaginary part of the complex number

Step-by-Step Breakdown of the Formula

To convert a complex number from rectangular form (a + bi) to polar form (r(cosθ + isinθ)), follow these steps:

  1. Identify the components: Determine the real part (a) and the imaginary part (b) of the complex number.
  2. Calculate the modulus: Use the formula r = √(a² + b²) to find the magnitude.
  3. Calculate the argument: Use the formula θ = arctan(b/a) to find the angle. Be aware of the quadrant in which the complex number lies for the correct angle measurement.
  4. Express in polar form: Combine the results to express the complex number as r(cosθ + isinθ).

Example Calculation

Let’s consider a real-world example with the complex number 3 + 4i. We will convert it to its polar form using the formulas provided.

Inputs and Outputs
Component Value
Real part (a) 3
Imaginary part (b) 4
Modulus (r) √(3² + 4²) = √(9 + 16) = √25 = 5
Argument (θ) arctan(4/3) ≈ 0.927 radians (or 53.13°)
Polar form 5(cos 0.927 + isin 0.927)

The complex number 3 + 4i can thus be expressed in polar form as 5(cos 0.927 + isin 0.927) or 5∠53.13°.
