GYM CAS
Anvend Python som CAS (Computational Algebra System) i gymnasiet. Bygger på følgende moduler:
- Algebra/beregninger:
- Afbildninger:
Udvikling
- Install uv
- Install tox:
uv tool install tox --with tox-uv - Create local virtual environment:
uv venv
- Run only tests (directly with uv):
uv run pytest tests - Run tests, coverage, lint, typecheck with tox (uv backend):
tox - Run venv:
uv run python
Publish with uv
- Setup PYPI token (powershell)
[System.Environment]::SetEnvironmentVariable("UV_PUBLISH_TOKEN", "pypi-...", "User")
$env:UV_PUBLISH_TOKEN = "pypi-..."
- Publish with:
uv publish
Installation
pip install gym-cas
eller
py -m pip install gym-cas
Cheatsheet
I nedenstående afsnit antages det at gym_cas først importeres således:
from gym_cas import *
B1. Tal- og bogstavregning
expand( udtryk )
factor( udtryk )
B2. Ligninger og uligheder
solve( udtryk )
solve( [udtryk1, udtryk2] )
nsolve( udtryk, startgæt )
solve_interval( udtryk, start, slut )
Opstille ligning
For at opstille en ligning kan man enten omforme sin ligning så en af siderne er lig 0 (og udelade 0) eller bruge Eq.
Ligningen x/2 = 10 kan skrives som x/2-10 eller som Eq(x/2, 10).
Ligningsløsning ved solve(x/2-10) eller solve(Eq(x/2, 10)) giver samme resultat.
B3. Geometri og trigonometri
Sin( vinkel )
Cos( vinkel )
Tan( vinkel )
aSin( forhold )
aCos( forhold )
aTan( forhold )
B4. Analytisk plangeometri
plot_points( X_list ,Y_list)
plot( funktion )
plot_implicit( udtryk ,xlim=( x_min, x_max),ylim=( y_min, y_max))
plot_geometry( Geometrisk objekt )
Flere grafer i en afbildning
p1 = plot( udtryk1 )
p2 = plot( udtryk2 )
p = p1 + p2
p.show()

a = vector(x,y)
a.dot(b)

plot_vector( start, vektor )
plot_vector( [vektor1, vektor2, ...])

def df(xi):
return diff( funktion ).subs( variabel, xi )
B10. Integralregning
integrate( udtryk )
integrate( udtryk, ( variabel, start, slut ))
plot3d_revolution( udtryk , (x, a, b),parallel_axis="x")

plot3d_plane( ligning, (x, x_min, x_max), (y, y_min, y_max), (z, z_min, z_max) )
plot3d_sphere( radius, centrum )
plot3d_implicit( ligning, backend=PB ) # Kræver Plotly eller K3D
A4. Differentialligninger
f = Function('f')
dsolve( ode )
plot_ode( ode, (x, start, stop), (f, start, stop))

X = [ startbetingelse ]
for i in range(start, slut):
X.append( rekursionsligning )
