Maple differential-ligninger
Benytter dsolve(ligning)
Eksempel med differential ligning: (y^{,}=2 – 3 cdot y(x))
(dsolve left ( diff left ( y(x) , x right ) =2 – 3 cdot y(x) right ))
Giver: (frac{2}{3} + e^{-3 cdot x} + Cl)
hvor Cl er en vilkårlig konstant, da det er en fuldstændig løsning.
Ønskes der at finde ligningen, der går gennem punkt, for eksempel (4,3),
tilføjes et ekstra argument, husk [ ]
(dsolve left ( left [ diff left ( y(x) , x right ) =2 – 3 cdot y(x) , y(4) = 3 right ] right ))
