America because the growing problem of Communists insurgents in the region
particularly in El Salvador, Guatemala and Nicaragua. The Cold War was still on and the U.S. feared
that Communism would take root in these areas and might threaten if they
continue unabated.
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
To help end the war and hopefully sustain peace through the fighting countries
