What Is It? - Racine Carree Calculator
This digital tool calculates square roots (√x) of any real or complex number, providing:
- Precise decimal results (up to 6 places)
- Complex number handling (for negative inputs)
- Interactive function graph
- Calculation history
The Formula
The fundamental operation follows:
√x = y where y² = x
For negative numbers:
√(-x) = i√x (where i is the imaginary unit)
