Q: What is the value of sin^(-1)(1/2) + sin^(-1)(√3/2)?
Solution:
sin^(-1)(1/2) = π/6 and sin^(-1)(√3/2) = π/3. Therefore, π/6 + π/3 = π/2.
Steps: 7
Show Steps
Step 1: Understand that sin^(-1)(x) means the angle whose sine is x.
Step 2: Find sin^(-1)(1/2). The angle whose sine is 1/2 is π/6 (30 degrees).
Step 3: Find sin^(-1)(√3/2). The angle whose sine is √3/2 is π/3 (60 degrees).
Step 4: Add the two angles together: π/6 + π/3.
Step 5: To add π/6 and π/3, convert π/3 to a fraction with a common denominator: π/3 = 2π/6.
Step 6: Now add π/6 + 2π/6 = 3π/6.
Step 7: Simplify 3π/6 to π/2.
