A partial di erential equation (PDE) for a function of more than one variable is a an equation involving a function of two or more variables and its partial derivatives. 1 Motivating example: Heat conduction in a metal bar A metal bar with length L= ˇis initially heated to a temperature of u 0(x). The temper-ature distribution in the bar is u ...

Nov 18, 2019 · Section 9-5 : Solving the Heat Equation. Okay, it is finally time to completely solve a partial differential equation. In the previous section we applied separation of variables to several partial differential equations and reduced the problem down to needing to solve two ordinary differential equations.

The heat equation is one of the most famous partial differential equations. It has great importance not only in physics but also in many other fields.

The heat equation is linear as u and its derivatives do not appear to any powers or in any functions. Thus the principle of superposition still ...

Aug 06, 2020 · With these quantities the heat equation is, c(x)ρ(x) ∂u ∂t = − ∂φ ∂x +Q(x,t) (1) (1) c ( x) ρ ( x) ∂ u ∂ t = − ∂ φ ∂ x + Q ( x, t) While this is a nice form of the heat equation it is not actually something we can solve. In this form there are two unknown functions, u u and φ φ , and so we need to get rid of one of them.
