Abstract:
If the $nth$ order differential equation is not exact, under certain
conditions, an integrating factor exists which transforms the differential
equation into an exact one. Thus, the order of differential equation can be
reduced to the lower order. In this paper, we present a technique for finding
integrating factors of the following class of differential equations:
Here, the functions F_{0},F_{1},F_{2},
…,F_{n} are assumed to be continuous
functions with their first partial derivatives on some simply connected domain
Ω ⊂ R^{n+1}.
We also presented some demonstrative examples
