• Oct 6, 2025 answers for no joking around trigonometric identities \sin 75^\circ + \sin 15^\circ\), apply the sum-to-product formula. Product-to-Sum: \(\sin A \sin B = \frac{1}{2} [\cos(A - B) - \cos(A + B)]\) \(\cos A \cos B = \frac{1}{2} [\cos(A - B) + \cos(A + B)]\) Solution By Otis Oberbrunner
