Formulas expressing trigonometric functions of an angle 2x (1). cos(2x), = cos^ 2x-sin^2x. (2). = 2cos^2x-1. (3). = 1-2sin^2x. (4). tan(2x), = (2tanx)/(1-tan^2x).

We start by using the Pythagorean trig identity and rearrange it for cos squared x to make expression [1]. This gives us. cos 2. ⁡.

cos(2x) = cos 2 (x) – sin 2 (x) = 1 – 2 sin 2 (x) = 2 cos 2 (x) – 1 Half-Angle Identities The above identities can be re-stated by squaring each side and doubling all of the angle measures. cos2x skulle jag hellre skriva som cos (2x), alltså Cosinus för dubbla vinkeln.
