Second-Order Ordinary Differential Equation -- from Wolfram MathWorld
Hello again
This time I have a question concerning the 2nd order homogeneous ODE and it's general solutions
in the following thread:
Homogeneous Linear Equations
they speak about it as having the general form:
y''[x] +p[x]*y'[x]+q[x]*y''[x] = 0
in the case where p[x] and q[x] are constant, one can easily obtain the general solution using the characteristic polynomial
my question: What do we do in all the other cases, when p[x] and q[x] are any other functions of x? (unfortunately they do not give a general solution to it in the thread)
with best regards, Marine
