Question on Partial Differential Equation
5.2 The linear model for vibrations of a rectangular drumhead is the wave equa- tion (4.30) with ...
A rectangular lamina of width a and height b is sandwiched between two slabs of ice, so that the lower and upper sides, of width a, are at a temperature Θ 0, The other two sides are thermally isolated. Fix coordinates so that the origin below is the lower left corner, as shown in the figure се се Model this situation as a temperature e(x, y,t) that satisfies the two-dimensional diffusion equation with thermal diffusivity D, namely ot together with...
