Question

find :-
\(\int e^{\frac{1}{z}}\)

Answer 1

not possible to find in terms of standard functions


or is the question incomplete ?

Answer 2

ok let say on complex plan :)

Answer 3

so,
\(\huge \int e^{\dfrac{1}{x+iy}}d(x+iy)
\quad ?\)

still not solvable

Answer 4

that would me complecated way to do it xD
but yeah ur right !

Answer 5

any idea ?

Answer 6

if it was solvable, i would have solved it.

Answer 7

you need the answer in terms of what ? like alpha beta functions ? bessel function ?

Answer 8

its solvable on closed interval lets say mmm
0<|z-z_0|<r

Answer 9

well , TBH the answer i have is 2pi i xD

Answer 10

constant answer...so integral must have some limits

Answer 11

yep

Answer 12

you want a contour integral?

Answer 13

yes ! lol
contour :O
i forget that lolz xD
ok continue plz

Answer 14

can you tell us the contour you want to integrate over?

Answer 15

you have to give us the path

Answer 16

0<|z-z_0|<r

Answer 17

are you going to tell us \(z_0\)? and the contour is the boundary of that open disk of radius \(r\)?

Answer 18

that what i really got , no more info :O

Answer 19

but i sound of got it nw
it only had one pranch cut at z=0
well thank you :D
