- 6Reduction of orderIf we know one solution of a 2nd homogenous equation, y(x)
We look for a second solution of the for
y = y(x)u(x)
Note: u(x) will be simpler - 7Variation of Parameters y''+p1(x)y'+p0(x)y=q(x)if we know y=Ay(x)+By(x) is a solution of the homogenous equation, then look solutions of the form
y=A(x)y(x)+B(x)y(x)
Differentiate and set A'y1 + B'y2 = 0
Find y' and y'' and sub. back into the original equation. Giving A'y1' + B'y2' = q(x)
Solve for A(x), B(x) - 82nd Order Linear Homogeneous ODE w. Constant coefficients y''+ay'+by=0
