I’m interested in solving the heat equation: d[K[z] d[T[z],z],z]=0, equipped with T(-h/2)=Tm and T(h/2)=Tc. Is it possible to get a symbolic solution in Mathematica using the power series method? The solution they provide in literature is attached in the picture. Where: K(z)=Km+(Kc-Km)(1/2+z/h)^n [![enter image description here][1]][1] [1]: https://i.sstatic.net/qD9pa.png
