Your cells are not infinitesimally small so it will be a bit more complicated than either formulation you have there. (The ``width'' of your finite volume cell varies nontrivially over the cell, so we ...

Is there a reason you considered the Fourier series? It actually seems fairly simple to compute $\frac{\partial T}{\partial t}$ as a piecewise function of $t$: $$ \frac{\partial T}{\partial t} = \...
