SUMMARY
The limit of the function \(\lim_{x\rightarrow 0} \frac{\sin 5x}{\sin 3x}\) can be solved using l'Hôpital's Rule or by applying the small-angle approximation for sine. As \(x\) approaches 0, \(\sin 5x\) approximates to \(5x\) and \(\sin 3x\) approximates to \(3x\). Therefore, the limit simplifies to \(\frac{5x}{3x} = \frac{5}{3}\), establishing that the limit is \(\frac{5}{3}\).
