Heres what I have...

can be rewritten as:

$\displaystyle

\frac{12(sinx)^3}{12x^3}=\frac{(sinx)^3}{x^3}=\fra c{sinx}{x}*\frac{sinx}{x}*\frac{sinx}{x}=1*1*1=1

$

Up to this point, am I correct? How does the fact that it wants the limit as x approaches zero from the left? I only know how to work with these one-sided limits in a peicewise function. What do I do from here & what do I need to learn to solve one sided limits that are NOT in a peicewise function?

Thanks!
