Number A called the limit function y = f(x) in point x0, if for any sequence of points from the domain of the function, distinct from x0, converging to a point x0(lim xn = x0), sequence of corresponding values of the function converges to the number A.
Example, find limit
Write as
lim x^3/exp(cosx) as x->infinity
and pressed on sign (=).
The same limit, but when x tends to 0. We write as
