Q
Q: Evaluate the expression sin^(-1)(x) + sin^(-1)(√(1-x^2)).
Solution:
Using the identity sin^(-1)(x) + sin^(-1)(√(1-x^2)) = π/2 for x in [0, 1], the value is π/2.
Steps: 6
Show Steps
Step 1: Understand the notation sin^(-1)(x). This represents the inverse sine function, also known as arcsin(x).
Step 2: Recognize that the expression sin^(-1)(x) + sin^(-1)(√(1-x^2)) involves two arcsin functions.
Step 3: Recall the identity that states sin^(-1)(x) + sin^(-1)(y) = π/2 when x and y are related by the equation x^2 + y^2 = 1.
Step 4: In our case, let y = √(1-x^2). Notice that x^2 + (√(1-x^2))^2 = x^2 + (1-x^2) = 1. This means the identity applies.
Step 5: Therefore, we can conclude that sin^(-1)(x) + sin^(-1)(√(1-x^2)) = π/2.
Step 6: Since this is true for x in the range [0, 1], we can state the final result.
