सहायक समीकरण के विभिन्न मूलों के लिए अवकल समीकरण का हल (पूरक फलन) नीचे दिखाया गया है।
सहायक समीकरण के मूल |
पूरक फलन |
m1, m2, m3, … (वास्तविक और भिन्न मूल) |
|
m1, m1, m3, … (दो वास्तविक और समान मूल)
|
|
m1, m1, m1, m4… (तीन वास्तविक और समान मूल) |
|
α + i β, α – i β, m3, … (काल्पनिक मूलों का एक जोड़ा) |
|
α ± i β, α ± i β, m5, … (समान काल्पनिक मूलों के दो जोड़े) |
|
गणना:
दिया है:
x = et रखने पर
⇒ t = ln x
अब, उपरोक्त अवकल समीकरण निम्न प्रकार बन जाती है
D(D - 1)y + 4 Dy + 2y = 0 ⇒ (D2 + 3D + 2)y = 0
⇒ D = -1, -2;
अब हल निम्न होगा y = C1e-t + C2e-2t
x = et के मानों को रखने पर
