The general solution of the homogeneous differential equation
3x?y" + 7xy + y = 0
can be written as
Ye = ax- + bx
where a, b are arbitrary constants and
Y, = 2 + 3x
is a particular solution of the nonhomogeneous equation
3x?y" + 7xy + y = 24x + 2
By superposition, the general solution of the equation 3x?y" + 7xy + y = 24x + 2 is y = y. + y, so
y
NOTE: you must use a, b for the arbitrary constants.
Find the solution satisfying the initial conditions y(1) = 9, y(1) = 9
y =
The fundamental theorem for linear IVPS shows that this solution is the unique solution to the IVP on the interval
The Wronskian W of the fundamental set of solutions y = x- and y, = x-1/3 for the homogeneous equation is
W = (2/(3x^(7/3))
