QuestionFind $\lim _{x \rightarrow \infty} \cos \left(\frac{1+\pi x}{x}\right)$.

Studdy Solution
The cosine of $\pi$ is -1. Therefore, the limit of the function as x approaches infinity is -1.
$$\cos \left(0+\pi \right) = -1$$So, $\lim{x \rightarrow \infty} \cos \left(\frac{1+\pi x}{x}\right) = -1$.
