Product-to-sum formulas are trigonometric identities that express the product of sines and cosines as a sum or difference of trigonometric functions, which is useful in simplifying integrals and solving trigonometric equations. These formulas are derived from the angle addition and subtraction identities and play a crucial role in Fourier analysis and signal processing.
