Evaluate the value of the infinite sum
sin⁻¹ ((1)/(√(2)))+sin⁻¹ ((√(2)-1)/(√(6)))+sin⁻¹ ((√(3)-√(2))/(√(12)))+⋯+sin⁻¹ ((√(n)-√(n-1))/(√(n(n+1))))+⋯.
- π/8
- π/4
- π/2
- π
Correct answer: π/2
Solution
The infinite sum converges to (C0)/(2) because each term in the series represents the inverse sine of a value that approaches the limit of 1 as n increases, leading to the cumulative angle approaching (C0)/(2).
