Definition

argument of $z$

argument de $z$

If $z = r e^{i φ}$ , where $r = | z |$ and $- π < φ \leq π$ , then $φ = arg z$ .

It holds $Re z = r cos φ$ and $Im z = r sin φ$ .

Si $z = r e^{i φ}$ , où $r = | z |$ et $- π < φ \leq π$ , alors $φ = arg z$ .

On a $Re z = r cos φ$ et $Im z = r sin φ$ .

A mathematical concept as defined in ISO/IEC 80000 Part 2.
