The Maple command for

is limit(f(x), x=a).
The following are some examples of the use of this command including some which are used in other Visual Calculus modules on limits.
> limit((x^2-5*x+4)/(x-1),x=1);
> limit(sin(x)/x,x=0);
> limit(sin(n*x)/x,x=0);
> limit(((x^3+8)^(1/3)-2)/x^3,x=0);

> limit(sin(10*Pi/x),x=0);
> limit(x*sin(1/x),x=0);
> limit((x^2+1)/(x-1),x=1);
> g:=x->abs(x)/x;

> limit(g(x),x=0);
> limit(g(x),x=0,right);
> limit(g(x),x=0,left);
> limit((1+x)^(1/x),x=0);
> limit((8^x-5^x)/x,x=0);
> k:=x->(3*x-15)/(x^2-10*x+25)^(1/2);

> limit(k(x),x=5);
> limit(k(x),x=5,right);
> limit(k(x),x=5,left);
