Hi All,

I'd be grateful if helped in this understanding;

I'm following the attached pages to solve a numerical problem by Forward difference, backward difference and central difference- in fact to be precise, deriving the transient solution approach to a heat transfer problem---

In the attached, pages 279 and 280 (don't worry I've not attached a 280 page book but just extracyed pages) derive a solution by forward difference

Pages 283-285 derive by backward and central difference,

He (the author) says forward and backward difference are different because the way the capacitance matrix i.e. [C] matrix and conductivity matrix i.e.[K] matrix are treated.I'm not able to apprciate the difference,Can anyone throw some light on this and explain the difference between forward and backwartd difference?
