**Newest 'linear-pde' Questions MathOverflow**

6/07/2009 · Hi. When solving a PDE by separation of variables, we obtain a collection of so-called normal modes. My book then tells me to make an "infinite linear combination" of these normal modes, and that this will be a solution to the PDE.... I understand the "general" point of view. It is just not trivial to me how we model PDE solving on a quantum computer. This is direct in HHL cause your problem can be expressed as a linear system Ax=f when you do discretization.

**Linear and Quasi-Linear PDEs Wolfram Language**

Quasi-linear PDE: A PDE is called as a quasi-linear if all the terms with highest order derivatives of dependent variables occur linearly, that is the coefficients of such terms are functions of only lower order derivatives of the dependent variables.... Definitions of Partial Differential Equations A partial differential equation is an equation that involves an unknown function and its partial derivatives. The order of the highest derivative defines the order of the equation. The equation is called linear if the unknown function only appears in a linear form. Finally, the equation is homogeneous if every term involves the unknown function or

**SOLUTION Explain how you can tell(without graphing**

Be sure to account for linear equations that are not functions. Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website! put both equations in slope-intercept form: y = mx + b---if the slopes are equal and the y-intercepts are equal, the equations describe the same line and the solution is infinitely many points. ---if the slopes are equal and the y-intercepts are how to keep graphics card cool Specifying partial differential equations with boundary conditions. DirichletCondition, NeumannValue and PeriodicBoundaryCondition all require a second argument that is a predicate describing the location on the boundary where the conditions/values are to be applied.
