Answer 1

false because the range is incorrect

Answer 2

the range is [-pi/2, pi/2]

Answer 3

@sourwing thanks a bunch! Mind telling me how you got that though?

Answer 4

it's just the definition of sin^-1(x).

Answer 5

those are the properties you need to memorize

Answer 6

@sourwing got it! Thank you so much!
