Cognos is a BI tool that was acquired by IBM. Business Intelligence usually refers to the 'data' team - most likely the data warehouse guys who would mine the data to prepare reports that will give insights to the senior leadership about various things - specially trends and patterns.
Thus, cosÂ²(36) = Â½ (cos(36) + Â½) = Â½ (cos(36) + cos(60)) = cos(48) cos(12) = cos(48) * 2 * cos(60) * cos(12) = cos(48) * (cos(48) + cos(72)) or (A): cosÂ²(36) - cosÂ²(48) = cos(48) cos(72) Now, we are ready to address the original problem, and assume each side length is 1.
