Modulus of a Complex Number (|z| = √(x² + y²))
jee-advancedjee-main
|z| = √(x² + y²)
What each symbol means
| Symbol | What it stands for |
|---|---|
| x | Real part Re(z) |
| y | Imaginary part Im(z) |
| z | Complex number x + iy with x, y ∈ ℝ |
| |z| | Distance of point (x,y) from origin in Argand plane |
When to use this
For z = x + iy, modulus is non-negative real length from origin. |z| = 0 iff z = 0.
