Аннотация: The article studies the characteristic equation arising in the problem of heating/cooling a hollow sphere under boundary conditions of the first kind using analytical methods. The obtained mathematical formulas make it possible to calculate the eigenvalues ${{\mu }_{n}}$ of this problem and determine the numerical values of the dimПоказать полностьюensionless temperature. Expressions for the eigenfunctions ${{K}_{n}}\left( \psi \right)$ and coefficients ${{A}_{n}}$ are also given. To improve calculation accuracy, the simple principle of subsequent approximation can be used by passing to the inverse function.
