Complex Number to Polar Form Calculator
Complex number to polar form calculator helps you rewrite a complex number from rectangular to polar form.

What Complex Number to Polar Form Calculator does
This calculator transforms a complex number from rectangular form (a + bi) into polar coordinates, outputting the magnitude (r) and phase angle (φ). Users enter the real and imaginary parts, and the tool provides the modulus and argument, enabling representation of the number using distance from the origin and angular direction. The conversion applies standard trigonometric principles to derive the polar equivalent of the input value. The results support work in mathematics, engineering, and physics contexts where polar notation is required. The output includes both the magnitude and the angle, formatted for immediate use in further calculations or documentation.

Complex Number to Polar Form Calculator FAQ
- How do I convert a complex number to polar form manually?
- To convert manually, calculate the magnitude using the Pythagorean theorem (r = sqrt(a² + b²)) and find the angle using the arctangent function (φ = arctan(b/a)), adjusting for the correct quadrant based on the signs of a and b.
- What does the magnitude represent in polar form?
- The magnitude (r) represents the distance from the origin (0,0) to the complex number in the complex plane, essentially the modulus of the number.
- Can this calculator handle negative real or imaginary values?
- Yes, the calculator processes both positive and negative values for the real and imaginary parts, automatically determining the correct phase angle based on the input coordinates.
- Is the angle output in degrees or radians?
- The material does not specify whether the angle is displayed in degrees or radians; users should check the calculator's settings or output format for unit details.
