Limit of sin(x) as x approaches infinity.
Understand the Problem
The question is asking for the limit of the sine function as the variable x approaches infinity. The sine function oscillates between -1 and 1, so we need to determine what happens to the limit of sin(x) as x grows indefinitely.
Answer
The limit of $\sin(x)$ as $x$ approaches infinity does not exist.

The limit of $\sin(x)$ as $x$ approaches infinity does not exist.
Steps to Solve
-
Recognizing the Behavior of Sine Function
The sine function, $\sin(x)$, oscillates between -1 and 1 for all real numbers. This means that for any value of $x$, $\sin(x)$ will always yield a result within this range. -
Analyzing the Limit as x Approaches Infinity
When we take the limit as $x$ approaches infinity, we are evaluating how $\sin(x)$ behaves as $x$ becomes extremely large. Since $\sin(x)$ continues to oscillate forever between -1 and 1, it does not settle down to a single value. -
Conclusion on the Limit
Since $\sin(x)$ does not approach a definitive value, we conclude that:
$$ \lim_{x \to \infty} \sin(x) \text{ does not exist.} $$
The limit of $\sin(x)$ as $x$ approaches infinity does not exist.
More Information
The sine function is periodic with a period of $2\pi$, causing it to repeat its values indefinitely. Because of this oscillatory nature, the limit does not settle on a single point, illustrating an important concept in calculus regarding limits of oscillating functions.
Tips
- Assuming that because $\sin(x)$ takes values between -1 and 1, the limit must be a number within that range. In reality, the oscillation means there is no single limit.
- Misunderstanding the definition of a limit can lead to incorrect conclusions about convergence.
