Math Problem Statement

Evaluate \( \lim_{{x \to 0}} \frac{\sin(8x)}{x} \).

Solution

The expression in the image appears to be:

limx0sin(8x)x\lim_{{x \to 0}} \frac{\sin(8x)}{x}

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

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

where kk is a constant. In this case, k=8k = 8. Therefore:

limx0sin(8x)x=8\lim_{{x \to 0}} \frac{\sin(8x)}{x} = 8

So, the result is 88.

Would you like more details, or do you have any questions?

Here are some related questions to further explore this concept:

  1. How would the limit change if the angle were sin(5x)\sin(5x) instead of sin(8x)\sin(8x)?
  2. Can we evaluate limx0sin(3x)sin(2x)\lim_{{x \to 0}} \frac{\sin(3x)}{\sin(2x)}?
  3. How would we handle limx0tan(8x)x\lim_{{x \to 0}} \frac{\tan(8x)}{x}?
  4. What happens if we evaluate limx0sin(8x)x2\lim_{{x \to 0}} \frac{\sin(8x)}{x^2}?
  5. Can we use L'Hôpital's Rule to solve this limit?

Tip: For limits involving trigonometric functions like sin(kx)\sin(kx) or tan(kx)\tan(kx) as x0x \to 0, remember that the limit sin(kx)xk\frac{\sin(kx)}{x} \to k simplifies calculations significantly.
