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

He worked well with the Soviet leader Nikita Khrushchev to thaw the cold war at the end of 1950s. In May 1960, their cooperation ended prematurely when diplomatic crises erupted because the Union of Soviet Socialist Republics (USSR) were said to have gunned down an American U-2 spy plane in Soviet air space.
President Eisenhower was compelled to admit to the soviets that the central intelligence unit of his country has been sending out spy missions for several years in the USSR.
