trigonometric form of a complex number
The trigonometric form of a complex number represents the number as a combination of its magnitude (or modulus) and angle (or argument) in a polar coordinate system. It is typically expressed as z = r(cos θ + i sin θ), where r is the magnitude and θ is the angle. This form allows for a simpler representation and calculation of complex numbers, especially when performing operations like multiplication and exponentiation.
