1. 서 론
열전달은 하나의 매체나 두 매체들 사이에 온도차가 존재할 때 일어나는 현상이다. 즉 온도가 다른 서로 다른 두 계를 접촉시키면 고온(내부에너지가 높은 계)의 분자들은 저온(내부 에너지가 낮은 계)의 분자로 이동하여 운동은 평균화하게 되는 것이다. 그러므로 heat transfer를 일으키는 원
In this project, solutions to second order linear recurrence equations with constant coeffi- cients have been investigated. We have used generating functions to derive the general solution to the homogeneous equation and we show that in general the particular solution is complicated to find. By limiting the right hand side (RHS) in the equation to a polynomial-exponential family of functions we c
