casify 0.6.18

A CAS-library wrapped around sympy to simplify use of CAS-functionality in mathematics.

casify

casify is a Python package that implements a simplified CAS (Computer Algebra System) for symbolic computation, wrapping around sympy for facilitate its computations. The implementation provides both Norwegian and English names for all of its functions.

Basic examples

Example 1: solving equations

from casify import *

solution = solve("x**2 - x - 6 = 0")
print(solution)

Eksempel 1: løse likninger

from casify import *

løsning = løs("x**2 - x - 6 = 0")
print(løsning)

Example 2: solve system of equations

from casify import *

solution = solve("x + y = 2", "x - y = -1")

print(solution)

Eksempel 2: løse likningssystemer

from casify import *

løsning = løs("x + y = 2", "x - y = -1")

print(løsning)

Example 3: function evalution

from casify import *

f = function("x**2 - x - 6")

print(f(2)) # Computes f(2)

Eksempel 3: funksjonsverdier

from casify import *

f = funksjon("x**2 - x - 6")

print(f(2)) # Regner ut f(2)

Example 4: Differentiation

from casify import *

f = function("x**2 - x - 6")


print(f.derivative()) # Gives the general expression for the derivative

print(f.derivative(2)) # computes f'(2)

Eksempel 4: Derivasjon

from casify import *

f = funksjon("x**2 - x - 6")

print(f.derivert()) # gir det generelle uttrykket for den deriverte

print(f.derivert(2)) # regner ut f'(2)

Example 5: algebraic expansion and factorization

from casify import *

print(factor("x**2 - x - 6"))  # faktoriserer x**2 - x - 6

print(expand("2*(x - 1) * (x + 4)"))  # utvider 2 * (x - 1) * (x + 4)

Eksempel 5: algebraisk utvidelse og faktorisering

from casify import *

print(faktoriser("x**2 - x - 6"))  # faktoriserer x**2 - x - 6

print(utvid("2*(x - 1) * (x + 4)"))  # utvider 2 * (x - 1) * (x + 4)
