About this calculator
The complex number square root calculator is a professional complex number calculation tool, used to calculate the square root and nth root of complex numbers. The square root of complex numbers has important applications in the fields of complex functions, signal processing, quantum mechanics and other fields. Unlike real numbers, the square root of a complex number has multiple values (nth root has n values), and this calculator will give all root values. Supports input and output in rectangular coordinate form (a+bi) and polar coordinate form (r∠θ), and automatically performs form conversion. De Moivre's theorem is used for calculations to ensure accurate and reliable results.
