We need $x>0$, then use
$$ (sin x)^x=e^{x log sin x}=e^{frac{log sin x}{frac1x}}$$

Use L'Hospital's rule to complete the standard exercise of finding that
$$ lim_{xto0}frac{sin x}{x}=1.$$
So we have that, as $xto0$, $sin xsim x$. Now the limit you have becomes
$$L=lim_{xto0}(sin x)^x = lim_{xto 0}x^x = lim_{xto0}e^{xln x}.$$
Now, take the log of this limit and find $ln L$. Once you've done that, just exponentiate this value to find $L$.
