The trigonometric formulas like Sin2x, Cos 2x, Tan 2x are popular as double angle formulae, because they have double angles in their trigonometric functions. For solving many problems we may use these widely. The Sin 2x formula is: Sin 2x = 2 sin x cos x S in2x = 2sinxcosx Sin 2x Cos 2x An identity is an equation that always holds true.

A trigonometric identity that expresses the expansion of sine of double angle in sine and cosine of angle is called the sine of double angle identity. Notice how a "co- (something)" trig ratio is always the reciprocal of some "non-co" ratio. You can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine. The following (particularly the first of the three below) are called "Pythagorean" identities.

cos(x)= cosx. tan(x) = tanx. cot(x) = cotx.
