In this exercise we have to calculate the value of the given function, so we have to:
[tex]csc(x) = sec (\pi /22)[/tex]
What is the cosecant function?
The cosecant function has the following characteristics will always be positive in the 1st and 2nd quadrant and negative in the 3rd and 4th quadrant.
Calculating the value of the function we have:
[tex]csc(x) = sec (\pi/2 - x)\\ = sec ( \pi/2 - 5\pi/11)\\ = sec (11\pi/22 - 10\pi /22)\\ = sec (\pi /22)[/tex]
