SUMMARY
The product of sines expression sin(2°) sin(4°) sin(6°)... sin(90°) can be expressed in the form (n√5)/2^50, where "n" is an integer. The solution involves transforming the product of sines into a sum using geometric series principles. Specifically, the geometric sum formula a/(1-r) is crucial for this transformation. Understanding this mathematical relationship is essential to derive the integer value of n.
