I seek the solution of the 4th order ordinary differential equation as follows:
d^4(y) / dx^4 + G * y = H
for the homogenous relation which is:
d^4(y) / dx^4 + G * y = 0
d^4(y) / dx^4 + 4*b^4 * y = 0
we assume the solution of the bellow form:
Now what is the private solution for the inhomogenous equation?
