Math Problem Statement

Lim of sin 5x/x

Solution

The limit you're asking for is:

limx0sin(5x)x\lim_{x \to 0} \frac{\sin(5x)}{x}

To solve this, we can use the standard limit property:

limx0sin(ax)x=a\lim_{x \to 0} \frac{\sin(ax)}{x} = a

In your case, a=5a = 5. Therefore:

limx0sin(5x)x=5\lim_{x \to 0} \frac{\sin(5x)}{x} = 5

So, the limit is 55.
