Q
Q: If sin^(-1)(x) + cos^(-1)(x) = π/2, then what is the value of x?
Solution:
Using the identity sin^(-1)(x) + cos^(-1)(x) = π/2, we can conclude that x can take any value in the range [-1, 1].
Steps: 4
Show Steps
Step 1: Understand the notation sin^(-1)(x) and cos^(-1)(x). These represent the inverse sine and inverse cosine functions, respectively.
Step 2: Recall the identity that states sin^(-1)(x) + cos^(-1)(x) = π/2 for any value of x in the range [-1, 1].
Step 3: Since the equation given in the question is exactly this identity, it holds true for all x in the range [-1, 1].
Step 4: Therefore, the value of x can be any number between -1 and 1, inclusive.
