The range of the function y = sin^(-1)(x) is:
  1. (0, π)
  2. [-π/2, π/2]
  3. [-1, 1]
  4. [0, 1]

Questions & Step-by-Step Solutions

The range of the function y = sin^(-1)(x) is:
  • Step 1: Understand what sin^(-1)(x) means. It is the inverse sine function, also known as arcsin(x).
  • Step 2: Know that the sine function (sin) takes an angle and gives a value between -1 and 1.
  • Step 3: The inverse sine function (sin^(-1)(x)) takes a value between -1 and 1 and gives back an angle.
  • Step 4: The angles returned by sin^(-1)(x) are limited to a specific range to ensure it is a function (one output for each input).
  • Step 5: The range of angles for sin^(-1)(x) is from -π/2 to π/2 radians.
  • Step 6: Therefore, the range of the function y = sin^(-1)(x) is [-π/2, π/2].
