Understanding Complex to Polar Form Conversion

A complex number can be represented in rectangular form as \(z = a + bi\), where \(a\) is the real part and \(b\) is the imaginary part. The polar form represents the same complex number using a magnitude (or modulus) \(r\) and an argument (or angle) \(\theta\).

Formulas

  • Magnitude (r): The distance from the origin to the point \((a, b)\) in the complex plane.

    Formula: \( r = \sqrt{a ^ (2 + b) ^ 2} \)

  • Argument (θ): The angle between the positive real axis and the line connecting the origin to the point \((a, b)\) in the complex plane, measured in radians.

    Formula: \( \theta = \operatorname{atan2}(b, a) \) (using atan2 to handle all quadrants correctly).
