You asked:

Evaluate the expression: \({\cos\left( \frac{6 \cdot \pi \cdot 6 \cdot 9}{\pi} \right)}^{2}\)

MathBot Answer:

\[{\cos\left( \frac{6 \cdot \pi \cdot 6 \cdot 9}{\pi} \right)}^{2} = \cos^{2}{\left(324 \right)} \approx 0.83673129842568308126103702600917\]

\[\begin{aligned}{\cos\left( \frac{6 \cdot \pi \cdot 6 \cdot 9}{\pi} \right)}^{2}& = \cos^{2}{\left(6 \cdot \pi \cdot 6 \cdot 9 \cdot \frac{1}{\pi} \right)}\\& = \cos^{2}{\left(36 \cdot \pi \cdot 9 \cdot \frac{1}{\pi} \right)}\\& = \cos^{2}{\left(324 \right)}\end{aligned}\]
