Is that the same as a pole of order zero? 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.

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...."

Unfortunately the relation "A loves B" is neither transitive, nor symmetric, nor reflexive ...
