In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle … See more By examining the unit circle, one can establish the following properties of the trigonometric functions. Reflections When the direction of a Euclidean vector is represented by an … See more Multiple-angle formulae Double-angle formulae Formulae for twice an angle. Triple-angle formulae See more For some purposes it is important to know that any linear combination of sine waves of the same period or frequency but different phase shifts is also a sine wave with the same … See more Euler's formula states that, for any real number x: These two equations can be used to solve for cosine and sine … See more These are also known as the angle addition and subtraction theorems (or formulae). The angle difference identities for $${\displaystyle \sin(\alpha -\beta )}$$ and $${\displaystyle \cos(\alpha -\beta )}$$ can be derived from the … 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 WebClub Z!
