Right, ty person ;)

But I thought the pole is z=1, no?

All I need is the result, so can u provide me with that? thx

anyone can help me with the integration please? f(z)=e1/z/(1-z) ∫f(z)dz around the circle |z|=1/2 ?

Im sry about that, yes integration around the circle .

Thx guys for these replies..I just want to know one last thing. using the residue theorem, what is the integral of f(z) ...at |z|=1/2 Thx again :)

at z°=1 here is how I've done it .. Res=limit [f(z)*(z°-z)] as z goes to z° =limit [e1/z/(1-z)*(z°-z)] as z goes to z° =limit [e1/z] as z goes to z° ''which equals to 1'' and finally I plugged in z=z°=1 and I got: Res=e1/1=e≈2.72 am I wrong somewhere?

Right :p the answer should be "exp"?

Hello guys, I just want to confirm about this problem ..Find the residue of this function: f(z)=e1/z/(1-z) Thx in advance.

Very helpful, thank you guys :)

what do u think about Fontys university? do u know any other universities that have Chemistry or Physics bachelor program?

if you've applied to all three of them, and get accepted, u must be a super genius or somthing, so where do u come from? and what are ur grades in high school ? which English test did u pass, and how much score did u get?

hello, thanks for ur reply. Well actually I am planing to go and study there, but I am worried about the admission, is it difficult to get accepted?

The only language I am comfortable with is English, and I am currently learning French which I am not really good enough to study with. also, I am ready to learn other languages as German and Spanish.
