How to Find the Tangent of the Sum or Difference of Angles
In the special cases of one of the diagonals or sides being a diameter of the circle, this theorem gives rise directly to the angle sum and difference trigonometric identities. The relationship follows most easily when the circle is constructed to have a diameter of length one, as shown here. See more 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 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 … 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.
