lim
I know I can use L'Hospital's but I want to understand this particular explanation. They seem to skip something, and I'm not seeing the connection:
The limit is \frac{6}{2}=3 since \lim_{x\to 0}\frac{\sin(x)}{x}=1
Answer
For x \neq 0 and x close to zero, we have
\frac{\sin 6x}{\sin 2x} = \frac{\sin 6x}{6x} \cdot \frac{6x}{\sin 2x} = 3 \cdot \frac{\sin 6x}{6x} \cdot \frac{2x}{\sin 2x}
See what to do now?
