Then solve for the initial conditions?
What about taking into account if
When , the DE is reduced to , and then we have
Find the basic function at for
Also, find the solution which satisfies
What I don't understand is why the book multiplied through by x instead of of z = x + yi, because looking at the first solution, the imaginary constant is being used in relations to sqrt{4-\lambda}.
How was acquired and is the coefficient 2 associated with sine in the first solutions due to solving for the conditions?
The solution to the problem is:
