x->0+\    2*sec(x)    /
$$\lim_{x \to 0^+}\left(\frac{\sin{\left(x \right)} \cot{\left(\pi x \right)}}{2 \sec{\left(x \right)}}\right)$$
Limit((cot(pi*x)*sin(x))/((2*sec(x))), x, 0)
Lopital's rule
There is no sense to apply Lopital's rule to this function since there is no indeterminateness of 0/0 or oo/oo type
