where C= column matrix of coefficients: C₁
Xn1.
b) Non-homogeneous system X' = AX + F(t)
Xin
X2n
Xnn
Particular Solution is:
Complementary solution is: X = (t)C,
C = C1
C2
T
Then
Cn
Xp= o(t) ¹(t)F(t)dt.
General solution of Nonhomogeneous equation: X' = AX + F(t)
Is X = (t)C+ (t)/ ¹(t)F(t)dt (1)
Solve the problem: X'= 0 2 X+ 1 e¹
-1 3
-1
Hint: first find the eigenvalues and corresponding eigenvectors for matrix.
Remember (t) is a matrix of solution vectors of homogeneous equation.
Then find ¹(t)
Then follow formula (1) find general solution of the given system.
