2. In lecture, we talked about the heat equation on a thin, laterally insulated rod. There are many other domains on which you might want to determine the temperature. In this question, we explore the temperature on a wire that has been formed into a circle. thin wire, length 2L, laying flat on [-L,L] bend wire into a circular shape result is a circular wire where the ends x=L and x=-L correspond to one point now. While the PDE remains...

Partial differential equation-heat equation,
The temperature distribution Θ(x, t) along an insulated metal rod oflength L is described by the differential equation.The rod is held at a fixed temperature of 0◦ C atone end and is insulated at the other end, which gives rise to the boundaryconditions Θ(0, t) = 0 and Θx(L, t) = 0, for t > 0.Show that function Xn(x) satisfies the boundary conditions that you found. Show that Xn(x) satisfies differential equation (1) for some constant µ (which you should...

A sheet of metal coincides with the square in the xy-plane whose vertices (0, O), (1 0), (1, 1) and (0, 1). The two faces of the sheet are insulated, and the sheet is so thin that heat flow in it can be regarded as two-dimensional. The edges parallel to the x- axis are insulated, and the left-hand edge is maintained at the constant temperature O. If the temperature distribution u(1, y) f(y) is maintained along the right-hand edge, Set...
