$\sin (2 π)$

Step 1

Find the value using the definition of sine.

$\sin (2 π) = \frac{opposite}{hypotenuse}$

Step 2

Substitute the values into the definition.

$\sin (2 π) = \frac{0}{1}$

Step 3

Divide $0$ by $1$ .

$0$

Step 4

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
