You asked:

Evaluate the expression: \(\sin\left( \frac{2 \cdot \pi}{7} \right)\)

MathBot Answer:

\[\sin\left( \frac{2 \cdot \pi}{7} \right) = \sin{\left(\frac{2 \pi}{7} \right)} \approx 0.78183148246802980870844452667406\]

\[\begin{aligned}\sin\left( \frac{2 \cdot \pi}{7} \right)& = \sin{\left(2 \cdot \frac{\pi}{7} \right)}\\& = \sin{\left(\frac{2}{7} \cdot \pi \right)}\end{aligned}\]
