(cosec45)^2*(sec30)^2*(sin90)^2*(cos60)
You asked:
Evaluate the expression: \({\csc\left( 45 \right)}^{2} \cdot {\sec\left( 30 \right)}^{2} \cdot {\sin\left( 90 \right)}^{2} \cdot \cos\left( 60 \right)\)
MathBot Answer:
\[{\csc\left( 45 \right)}^{2} \cdot {\sec\left( 30 \right)}^{2} \cdot {\sin\left( 90 \right)}^{2} \cdot \cos\left( 60 \right) = \sin^{2}{\left(90 \right)} \cos{\left(60 \right)} \csc^{2}{\left(45 \right)} \sec^{2}{\left(30 \right)} \approx -44.1853141313013089024653284707527\]
