These are questions asked by marians

 

I need to calculate the following complex integral:

oint_C { [(z^4exp(2z)+1)/(z+i)^3] - [(z^3+z)/{(z-2i)(z-5)}] + 8*Pi*exp } dz,

 

Where C is the circumference |z-1| = sqrt(11/2), positively oriented.

 

Someone can help me, I already researched but I can not integrate.

Good evening,
I know the plot package and use frequently, but the basics. Now I need to make a curve that looks like an " umbrella " and it appears the projection in the xy plane . I don't know if it's possible , but I'm not getting . Does anyone have any idea to help me ? Thank you!

restart; with(GroupTheory)

``

d := Perm([[1, 2, 3, 4, 5]]);

Perm([[1, 2, 3, 4, 5]])

 

Perm([[1, 3], [4, 6], [5, 7]])

(1)

G := PermutationGroup({d, e});

GroupTheory:-PermutationGroup({thismodule, object}, )

(2)

H := Elements(G):

"A:=select(H[i]->PermOrder(H[i])=4,i=1..nops(H));"

Error, invalid operator parameter name

"A:=select(H[i]->PermOrder(H[i])=4,i=1..nops(H));"
