i have such a function(adsbygoogle = window.adsbygoogle || []).push({});

[tex]

z^3 \sin \frac{1}{3}

[/tex]

i need to calculate its residium at z=infinity

if i substitue infinity instead of a"" into the formal formula

[tex]res(f(x),a)=\lim_{x->a}(f(x)(x-a))[/tex]

i get infinity

am i correct?
