Geometrically, these are See more These are also known as the angle addition and subtraction theorems (or formulae). The angle difference identities for These identities are … See more The product-to-sum identities or prosthaphaeresis formulae can be proven by expanding their right-hand sides using the angle addition theorems. Historically, the first four of these were known as Werner's formulas, after Johannes Werner who used them for … See more These identities, named after Joseph Louis Lagrange, are: A related function is the Dirichlet kernel: See more By examining the unit circle, one can establish the following properties of the trigonometric functions.
