Jan 19, 2022 · Undetermined Coefficients Method. Given a nonhomogeneous ordinary differential equation, select a differential operator which will annihilate the right side, and apply it to both sides. Find the solution to the homogeneous equation, plug it into the left side of the original equation, and solve for constants by setting it equal to the right side.

Undetermined Coefficients. To keep things simple, we only look at the case: d2y dx2 + p dy dx + qy = f (x) where p and q are constants. The complete solution to such an equation can be found by combining two types of solution: The general solution of the homogeneous equation. d2y dx2 + p dy dx + qy = 0.
