Hi Emmanuel,
Thank you for your reply. Given the preliminary declarations
> *x = var("x")*
*h(x) = (x^2 + x + 2)/(x - 4)*,
I've discovered that
*limit(**h**, x=4, dir="right")*
gives the confusing answer
*x |--> +Infinity* ,
but that by replacing *h* by *h(x)* one obtains the desired
Let's see :
sage: h(x)=(x^2+x+2)/(x-4)
sage: h.parent()
Callable function ring with argument x
sage: limit(h,x=4,dir="right").parent()
Callable function ring with argument x
sage: h(x).parent()
Symbolic Ring
sage: limit(h(x),x=4,dir="right").parent()
Symbolic Ring
sage: limit(h(x),x=4,dir="right")
