Complex numbers

Once again the sympy module will be used. We only need to import part of the module to manipulate complex numbers:

from sympy import Abs, Symbol, S, I

Manipulating complex numbers

Complex numbers can be written like this 2*I+3.

Here is a list of the essential functions:

• re(x) returns the real part of a complex number x
• im(x) returns the imaginary part of a complex number x
• abs(x) returns the absolute value of the argument of a complex number x
• arg(x) returns the argument (in radians) of a complex number x
• conjugate(x) returns the conjugate of a complex number x
