**Reiny**, Tuesday, January 14, 2014 at 11:01pmfirst question is correct

#2 should be true.

sin^-1 (x) means find the angle Ø so that sinØ = x

since the result of taking the sine is always a number between -1 and +1

then for sin^-2 (x) , your choice of x has to be -1 ≤ x ≤ 1

e.g try taking sin^-1 (1.4) on your calculator

that is

2nd

sin

1.4

=

you should get an "error" result
