You asked:

Evaluate the expression: \(\sin\left( \frac{3 \cdot \pi}{4} \right)\)

MathBot Answer:

\[\sin\left( \frac{3 \cdot \pi}{4} \right) = \frac{\sqrt{2}}{2} \approx 0.70710678118654752440084436210485\]

\[\begin{aligned}\sin\left( \frac{3 \cdot \pi}{4} \right)& = \sin{\left(3 \cdot \frac{\pi}{4} \right)}\\& = \sin{\left(\frac{3}{4} \cdot \pi \right)}\\& = \frac{1}{2} \cdot \sqrt{2}\end{aligned}\]
