Hahaha It is kinda opposite. You get the order of a zero at a by dividing by (z-a)^m. It is the maximum m such that f(z)/(z-a)^m is still holomorphic at a. In the powerseries development it is the index of the first non-zero term, e.g. f(z) = f_m (z-a)^m + f_{m+1)(z-a)^{m+1} + .... So f(z)/(z-a)^m can not be 0 at a. carrythomas Unregistered   11/09/2009, 08:34 AM Hi all, Once a boy proposed to girl who is the daughter of his maths sir, now he want to proposed her in a class. He stand up and go to blackboard. He try to say something from this Eqation "A=B=C, so A=B, B=C and B=A, B=C i.e A=C" Sir doesn't understand and he asked to him, what is this?? He replied "A=me, B= You, C= Your Daughter.. now A=B,B=C that means I love You, You love your Daughter.. B=A,B=C means You love me, You love your Daughter, So A=C means I love your Daughter...." bo198214 Administrator Posts: 1,391 Threads: 90 Joined: Aug 2007 11/09/2009, 09:32 AM Unfortunately the relation "A loves B" is neither transitive, nor symmetric, nor reflexive ... « Next Oldest | Next Newest »
