A Particular Solutions Formula For
Inhomogeneous Second Order
Linear Ordinary Differential Equations
© 2011 Claude Michael Cassano
Finding a particular solutions to a linear inhomogeneous ordinary differential equation has always been a process of determining homogeneous solutions, and then adding any particular solution of the inhomogeneous equation. The well-known methods of undetermined coefficients and
variation of parameters have long been the standard in determining...

A Helmholtzian operator is a linear second order partial differential operator, typically in four independant variables; a generalization of the d'Alembertian operator where it's additional constant vanishes. When the time-independant version (in three independent (space) variables acting on a function or vector vanishes, the resulting equation is called the Helmholtz's equation. In four dimensions this equation is referred to as the Klein-Gordon equation (with imaginary constant) .

Dear Sir/Madam,
i am honored to tell you that Chen Minglou’s important painting Imperial City of the Southern Song Dynasty has been finished after five years ‘hardworking..
The painting is half a meter in width, more than 28 meters in height. Size of people, buildings and other articles in the Painting for Imperial City of the Southern Song Dynasty is almost same with those in the “Along the River During the Qing Ming Festival”showed on the 2010 shanghai Expo, but the...

The d'Alembertian is a linear second order differential operator, typically in four independant variables. The time-independant version (in three independent (space) variables is called the Laplacian operator. When it's action on a function or vector vanishes, the resulting equation is called the wave equation (or Laplace's equation). When it's action is identified with a non-zero function (or vector function) the resulting equation is called Poisson's equation. This equation is fundamental...

A fourth grade teacher describes strategies she uses to structure individual lessons in her elementary school classroom. In the video you will notice biomedical science students from Charles Drew University of Medicine and Science observing Ms. Thai in her classroom prior to starting their mentoring activities with the elementary school students.
