Two trig identities are of interest here:
... sin(x)² + cos(x)² = 1
... csc(x) = 1/sin(x)
Using the first one, you can subtract cos(x)², the take the square root to find
... sin(x) = ±√(1 - cos(x)²)
Using that in the second one, you have
... csc(x) = ±1/√(1 - cos(x)²) . . . . . . . . . . . . . matches the 3rd choice
Going to court to get a particular ruling is called <span>litigation.
Have a nice day! :)</span>
Well, I cant give you the answer, but I can tell you that the Religion started in Saudia Arabia... this should give you a pretty clear hint! ;)
