  1. y = x
  2. y = -x
  3. y = 1-x
  4. y = 1+x

Questions & Step-by-Step Solutions

If y = sin^(-1)(x), then x = sin(y) implies:
  • Step 1: Understand that sin^(-1)(x) means the inverse sine function, which gives you an angle y such that sin(y) = x.
  • Step 2: If we say y = sin^(-1)(x), it means we have found an angle y for which the sine of that angle equals x.
  • Step 3: The equation x = sin(y) is simply stating that if you take the sine of the angle y, you will get back x.
  • Step 4: Therefore, by the definition of the inverse sine function, if y = sin^(-1)(x), then it is true that x = sin(y).
