So the solution of a differential equation is a function of t (when t is the independent variable) and odesolve allows us to get the value of this function for a particular value of t. In many cases it is possible, not only to get the value of y for one particular value of t but to get the solution in the form of an exact function of t.

(x + y) dy+(x – y)dx = 0,y = 1 when x = 1 In mathematics, the annihilator method is a procedure used to find a particular solution to certain types of non-homogeneous ordinary differential equations (ODE's). It is similar to the method of undetermined coefficients, but instead of guessing the particular solution in the method of undetermined coefficients, the particular solution is determined systematically in this technique. A point load can be mathematically represented as a distribution, e.g., a Dirac delta. It breaks the Gridap flow, since one cannot use Gauss quadratures and numerical integration (what we usually do in FEM) to compute the integral of f*v in that case. Particular solution definition, a solution of a differential equation containing no arbitrary constants. See more.
