Dear all, I have the following Partial Differential Function. It's a Secondorder variable coefficient homogeneous linear differential equation. (A.Y')+CY=0 in which A and Y are functions of x, C is a nonzero constant. A is not an elementary function. So is it possible to represent Y in terms of A or A'? When C is zero, it is quite easy. Y is the harmonic average of A. When C is nonzero, is it possible to write Y in terms of A?

Why "second order" and why "partial"?
