SUMMARY
The discussion focuses on calculating the area under the curves defined by the equations y = cos x and y = sin 2x over the interval [0, π/2]. The points of intersection are identified as x = π/6 and x = π/2. The correct formulation for the area is established as the sum of two integrals: [ S(0, π/6) (cos x - sin 2x) ] + [ S(π/6, π/2) (sin 2x - cos x) ]. The importance of ensuring that the area calculation remains positive is emphasized, clarifying that the area should not include negative values unless specified otherwise.
