## Homework Statement

lim x-->0 sin(pi/x) sqrt(x^3+x^2)

## The Attempt at a Solution

I was having trouble evaluating the above limit. Do I start by isolating x? For some reason, when it comes to trig functions such as this, I'm not sure how to simplify it. Also, what material would I have to review for me to understand how to break down such trig functions? I'm aware of fundamental, quotient and reciprocal identities of trig functions but am not sure how to use that knowledge to solve these type of problems.
