csc(3 $\pi$ /2)
You asked:
Evaluate the expression: \(\csc\left( \frac{3 \pi}{2} \right)\)
MathBot Answer:
\[\csc\left( \frac{3 \pi}{2} \right) = -1\]
\[\begin{aligned}\csc\left( \frac{3 \pi}{2} \right)& = \csc{\left(3 \cdot \frac{\pi}{2} \right)}\\& = \csc{\left(\frac{3}{2} \cdot \pi \right)}\\& = -1\end{aligned}\]
