Complex numbers
1) Formula of Euler :
2) Module of a complex number to ib:
3) Argument of a complex number to ib:
4) cartesian Representation of a complex number :
5) trigonometrical Representation of a complex number :
6) exponential Representation of a complex number :
is clearly therefore that |and the q | = 1
7) Describe the module and the phase of the n° complex turning out from the product of 2 complex numbers :
The module is the product of the modules and the phase is the sum of is made.
8) Describe the module and the phase of the n° complex turning out from the relationship of 2 complex numbers :
The module is the relationship of the modules and the phase is the difference of is made.
9) 
:
| z |2
10) 
:
2Re(z)
11) 
:
2Im(z)
12) Calcolo of the root n-esima of a complex number :
It can easily be written in exponential shape where the
module is worth rn while the argument is
