# Math Help - Calculus, limits

1. ## Calculus, limits

determine, using the properties of limits : limx->0 f(x) - 3x / f(x) +x^2
given Limx->0 f(x) = 0.

What happens in each of these two cases:
$f(x)=\sin(x)~\text{or}~f(x)=x^2$.

3. i'm not sure, I was never taught in detail, this is the first time I have ever seen a question where I needed to use limit properties. Basically i'm trying to teach myself this stuff.
