Math Problem Statement

What is the limit of (sin(2x))/(3x) as x approaches infinity?

Solution

The image contains a mathematical expression that appears to be a limit problem:

limx(sin(2x)3x)\lim_{x \to \infty} \left( \frac{\sin(2x)}{3x} \right)

Solving the Limit:

To solve this limit, let's analyze the expression:

limx(sin(2x)3x)\lim_{x \to \infty} \left( \frac{\sin(2x)}{3x} \right)

  1. Bounded Nature of Sine Function:
    The sine function, sin(2x)\sin(2x), is bounded between -1 and 1 for all values of xx: 1sin(2x)1-1 \leq \sin(2x) \leq 1

  2. Considering the Entire Expression:
    When dividing the sine function by 3x3x, as xx approaches infinity, the denominator 3x3x grows without bounds. Therefore, the fraction sin(2x)3x\frac{\sin(2x)}{3x} becomes smaller and smaller in magnitude.

  3. Squeeze Theorem Application: Since 13xsin(2x)3x13x-\frac{1}{3x} \leq \frac{\sin(2x)}{3x} \leq \frac{1}{3x}, and both 13x\frac{1}{3x} and 13x-\frac{1}{3x} tend to 0 as xx \to \infty, by the Squeeze Theorem, the limit of the original expression is also 0.

Thus, the limit is:

0\boxed{0}
