Math Problem Statement

lim(x->0) sin(x) / (3x^2 + 2)

Solution

The problem you've uploaded asks for the following limit evaluation:

limx0sinx3x2+2\lim_{x \to 0} \frac{\sin x}{3x^2 + 2}

Let's break it down:

Step 1: Substitute x=0x = 0

We start by attempting direct substitution of x=0x = 0 into the expression:

sin(0)3(0)2+2=00+2=02=0\frac{\sin(0)}{3(0)^2 + 2} = \frac{0}{0 + 2} = \frac{0}{2} = 0

Step 2: Interpret the limit

Since substituting x=0x = 0 results in a straightforward answer of 0, there's no need for advanced techniques like L'Hopital's Rule.

Therefore, the correct value of the limit is:

limx0sinx3x2+2=0\lim_{x \to 0} \frac{\sin x}{3x^2 + 2} = 0

However, the options provided don't include this result, which suggests there might be a typo or missing details. Double-checking the question or choices may help clarify. If you're certain of the options, let me know.

Would you like more detailed steps or clarification on any part? Here's a tip: When solving limits, always check if direct substitution leads to indeterminate forms like 00\frac{0}{0} or \frac{\infty}{\infty}. If not, simple evaluation can suffice!

Here are 5 related questions you might find useful:

  4. How do you find limits of rational functions as x0x \to 0?
  5. What role does continuity play in evaluating limits?

Tip: When evaluating limits, check if the numerator and denominator approach 0, indicating the potential for using L'Hopital's Rule.
