Expert-verifiedVerify that the solution to the initial value problem
Satisfies as
The solutions for the given initial value problem are
and . Then, it satisfies the also.
Elimination Procedure for 2 × 2 Systems:
To find a general solution for the system;
Where and are polynomials in :
Given that,
To verify: as .
Let us rewrite this system of operators in operator form:
Multiply 4 on equation (3) and D-5 on equation (4). Then, add them together to get,
Since the corresponding auxiliary equation is . The roots are and .
Then, the homogeneous solution is
Let us take the undetermined coefficients and assume that
Now derivate the equation (7)
Substitute the derivation in equation (5).
So, .
Then,
Substitute equation (8) in equation (4).
Given, .
Now substitute the values in equations (8) and (9).
First, solve the equations (10) and (11).
Then,
Now substitute the values of c in equations (8) and (9).
Now calculate the limits:
So, the solution is founded.
