csc(1/√2) is very unusual. It is 1.5393...
1/√2 is not an angle you see very often.
sin-1(1/√2) = π/4
It is an angle whose sine is 1/√2
since csc(π/4) = √2,
csc-1(√2) = π/4
In general,
sin-1 x = csc-1 1/x
what is the difference between csc (1/sqrt 2) and sin^-1 (1/sqrt 2) and determine their values
