Converting Rectangular to Polar Form

To convert a complex number from rectangular form a + bi to polar form r∠θ, compute the modulus r = √(a² + b²) using the Pythagorean theorem, and the argument θ = atan2(b, a) using the inverse tangent that accounts for all four quadrants. The result is the same number expressed as a distance and angle from the origin.
