QuestionFind $\lim _{x \rightarrow 0} \frac{\cos 2 x}{3}$. Choose from: A) 0 B) $\frac{1}{3}$ C) $\frac{2}{3}$ D) does not exist.

Studdy Solution
Substitute the value of $\cos0$ which is $1$.
$$\frac{1}{3}$$So, the result of $\lim{x \rightarrow0} \frac{\cos2x}{3}$ is $\frac{1}{3}$, which corresponds to option B.
