Hey guys(adsbygoogle = window.adsbygoogle || []).push({});

Basically I want to evaluate ((1/3 +x/2 +x^{3}/6))^{3}

But instead of doing the long hand is there any way off doing this quickly? Basically I was wanting to find the coefficient of x^{3}?

So ya any tricks because I seem to remember doing something like 3(1/3*1/2*1/6) +... can't remember..

Thanks in advance!!

Regards

Tam
