## Manipuler des polynômes
|
||||
|
||||
### Les représentations des polynômes
|
||||
|
||||
>>> P = Polynom([1, 2, 3])
|
||||
>>> print(P)
|
||||
|
||||
### Évaluer des polynômes
|
||||
|
||||
>>> type(P(3))
|
||||
pymath.expression.Expression
|
||||
>>> for i in P(3).simplify():
|
||||
print(i)
|
||||
3 \times 3^{ 2 } + 2 \times 3 + 1
|
||||
3 \times 9 + 6 + 1
|
||||
27 + 6 + 1
|
||||
33 + 1
|

### Opération et polynômes

|
||||
>>> for i in (P+1):
|

3 x^{ 2 } + 2 x + 1 + 1
|

3 x^{ 2 } + 2 x + 2
|
||||
>>> Q = Polynom([4, 5, 6])
|
||||
>>> for i in (P+Q):
|
||||
print(i)
|
||||
3 x ^ 2 + 6 x ^ 2 + 2 x + 5 x + 1 + 4
