The final answer is 0

Steps to Solve

  1. Recall the periodicity of the sine function

The sine function has a period of $2\pi$, which means $\sin(\theta) = \sin(\theta + 2k\pi)$ for any integer $k$. Therefore,

$$\sin(2\pi) = \sin(0 + 2\pi) = \sin(0)$$

  1. Evaluate $\sin(0)$

From the unit circle, we know that the sine of $0$ radians is $0$.

$$\sin(0) = 0$$

Therefore,

$$\sin(2\pi) = 0$$

The final answer is 0

More Information

The sine function has a periodicity of $2\pi$, so $\sin(2\pi)$ is equivalent to $\sin(0)$. Since $\sin(0) = 0$, $\sin(2\pi)$ also equals $0$.

Tips

A common mistake is to overlook the periodic nature of the sine function and not use the fact that $\sin(2\pi)$ is equivalent to $\sin(0)$.
