$lim_{x \to \infty} \frac{\sin (x)}{e^{x} + \cos (x)}$

Etapa 1

Como $\frac{- 1}{e^{x} + \cos (x)} \leq \frac{\sin (x)}{e^{x} + \cos (x)} \leq \frac{1}{e^{x} + \cos (x)}$ e $lim_{x \to \infty} \frac{- 1}{e^{x} + \cos (x)} = lim_{x \to \infty} \frac{1}{e^{x} + \cos (x)} = 0$ , aplique o teorema do confronto.
