Suppose that a finite-difference solution has been obtained for the temperature T, near but not at an adiabatic boundary. in most instances, it would be necessary or desirable to evaluate the temperature at the boundary point itself. for this case of an adiabatic boundary, develop an expression for the temperature at the boundary T1, in the terms of temperatures at neighbouring points T2, T3, etc, by assuming that the temperature distribution in the neighbourhood of the boundary is

  • a straight line
  • a second-degree polynomial
  • a cubic polynomial (you only need to indicate how you would derive this one)

indicate the order of T.E in each of the above approximations used to evaluate T1
