cos 31pi/12
You asked:
Evaluate the expression: \(\frac{\cos\left( 31 \right) \cdot \pi}{12}\)
MathBot Answer:
\[\frac{\cos\left( 31 \right) \cdot \pi}{12} = \frac{\pi \cos{\left(31 \right)}}{12} \approx 0.23947898926717679447213086897944\]
\[\begin{aligned}\frac{\cos\left( 31 \right) \cdot \pi}{12}& = \cos{\left(31 \right)} \cdot \frac{\pi}{12}\\& = \frac{\pi}{12} \cdot \cos{\left(31 \right)}\end{aligned}\]
