6. can you use lhopitals rule to solve lim x→0 cos(3x)/3x yes no

Explanation:

Step1: Check limit form

When (x\rightarrow0), (\cos(3x)\rightarrow\cos(0) = 1) and (3x\rightarrow0). The limit (\lim_{x\rightarrow0}\frac{\cos(3x)}{3x}) is in the form (\frac{1}{0}), not in the (\frac{0}{0}) or (\frac{\infty}{\infty}) form required for L'Hopital's Rule.

Answer:

No
