These can all be solved by employing a set of trigonometric identities known as the sum and difference formulae, which tell you how to compute the sine or cosine of the *sum* (or difference) of ... WebTrigonometric Identities. In algebraic form, an identity in x is satisfied by some particular value of x. For example (x+1) 2 =x 2 +2x+1 is an identity in x. It is satisfied for all values of x. The same applies to trigonometric identities also. The equations can be seen as facts written in a mathematical form, that is true for “ right angle ...
