Non-Homogeneous Linear Partial Differential Equations (PDEs) feature a non-zero function on their right-hand side, essential for modeling physical phenomena under external forces. The general solution combines the complementary function (CF) of the homogeneous equation with a particular integral (PI). Various solving techniques include the operator method, method of undetermined coefficients, and variation of parameters, which are crucial for tackling advanced engineering problems.
