Discrimant classification b^2 - ac <, = , > >0 => PDE is Hyperbolic =0 => PDE is Parabolic
Reduction of order If 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
Variation 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)
