Some second-order equations, e.g.,
xy^('')=y^('),
can be solved by using the substitution p(x)=y^(')(x). This substitution will convert the second-order differential equation to a first-order problem. This method is called reduction of order. Use the give substitution to solve for a general solution of (1).
