# if the function goes out of its domain while calculating the limit of that function, can we say that the limit does not exist?

example:
Calculate the limit of a function, while x approaches -1
f(x)=x+arccos(x/1-x^2)-1/(x^2)*e^(1/2*x^2)
//the function arccosX (X is a real number) is defined for X∈[-1,1], but in this function, while x approaches -1, we get arccos(-1/0)=arccos(infinity)
