Reduction of Order
www.cliffsnotes.com › reduction-of-orderThe method for reducing the order of these second‐order equations begins with the same substitution as for Type 1 equations, namely, replacing y′ by w. But instead of simply writing y ″ as w ′, the trick here is to express y ″ in terms of a first derivative with respect to y .

Reduction of Order
howellkb.uah.edu › DEtext › Part3The “reduction of order method” is a method for converting any linear differential equation to another linear differential equation of lower order, and then constructing the general solution to the original differential equation using the general solution to the lower-order equation.
Reduction of order - Wikipedia
https://en.wikipedia.org/wiki/Reduction_of_orderReduction of order is a technique in mathematics for solving second-order linear ordinary differential equations. It is employed when one solution is known and a second linearly independent solution is desired. The method also applies to n-th order equations. In this case the ansatz will yield an (n−1)-th order equation for .
