What is the Complex Number Calculator?
Enter two complex numbers like 3+4i and 1-2i and pick an operation. The tool shows the answer in rectangular form (a + bi), polar form (r∠θ), the modulus and the argument in degrees and radians. It also handles expressions such as (2+3i)^2 or sqrt(-16).
How to use the Complex Number Calculator
- Enter z1 and z2 (use i for the imaginary unit).
- Choose an operation or type your own expression.
- Read the rectangular and polar forms.
What is the modulus?
The modulus |z| is the distance of the number from 0 on the complex plane: √(a² + b²).
