* lim internal
lim(y, x = x0)
It finds the limiting value of y when x = x0.
lim(y, x = x0+zero)
It finds the right-sided limit as x approches to x0 from the positive
(+inf) direction (x = x0+).
lim(y, x = x0-zero)
It finds the left-sided limit as x approches to x0 from the negative
(-inf) direction (x = x0-).
Note that the correct answers are usually for the indeterminate forms:
0/0, inf/inf, 0*inf, 0^0, inf^0.
See also: zero, replace.
e.g. lim(sin(x)/x, x = 0) gives 1.
