SISTEM SATU KOMPONEN

Aturanfasa:

• Variabelsistem: P, T

Calculate:

(determinant)

Case 1: D > 0

1 real root and 2 imaginary roots

Case 2: D = 0

three real roots and at least two are equal

Case 3: D < 0

three, distinct, real roots

Where k = 0 for i = 1

k = 1 for i = 2

k = 2 for i = 3

The minus sign applies when L > 0,

The plus sign applies when L < 0.
