it is only a mere curiosity of calculus and do not if has any application

the idea is how can we define the apparently impossible functions

for m a real number

s+a >0

a can be a real or complex number

a and b are real numbers a,b >0

but 'f' is a complex valued function even for real 'x'

as you can see all of them make no sense for any x real or complex since we always would have the same answer

for every real or complex 'x'
