sorry for responding after such along time. 'was sick & hence away from my institute. thanx halllsofivy, but i did not ask how to prove that continuity of p.der of f wrt y was a sufficient condition, rather i wanted to know if it is possible to EXPLAIN this requirement in simpler terms ! let...

don't mind but what do u'r short forms , viz 1)fem 2)bem 3)fdm 4)fvm mean?

hi , i want to know if anybody can point me to some microscopic model which explains why light bends at the interface of 2 media? i am not asking for an exact mathematical model (although such a thing would be nice). an well founded physical explanation would be enough for me.

guys,was just reading diff.eqns by ross. uniqueness of an 1-d d.eqn of the form y'=f(x,y) is said to be guaranteed when i>partial der.of f(x,y) w.r.t y is a continuous of x & y over the same domain D over which f(x,y) is defined & is continuous. can somebody explain how this condition...
