Method of trial solution (undetermined coefficients)
This method is also known as the method of undertermined coefficients; the terminology "trial solution" is more descriptive since the method involves guessing the solution mathematical expression, called the trial solution, which have unknown coefficients to be determined by substituting the trial solutions into the differential equation.
