List of trigonometric identities wikipedia
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 … Meer weergeven 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 … Meer weergeven 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 … Meer weergeven These identities, named after Joseph Louis Lagrange, are: A related function is the Dirichlet kernel: Meer weergeven These are also known as the angle addition and subtraction theorems (or formulae). The angle … Meer weergeven Multiple-angle formulae Double-angle formulae Formulae for twice an angle. Triple-angle … Meer weergeven For some purposes it is important to know that any linear combination of sine waves of the same period or frequency but different Meer weergeven Euler's formula states that, for any real number x: These two equations can be used to solve for cosine and sine in terms of the exponential function. Specifically, These formulae are useful for proving many other … Meer weergeven WebThe trigonometric functions of angles that are multiples of 15°, 18°, or 22.5° have simple algebraic values.
