: Let (t = \sin x). Then (2t^2 - t - 1 = 0).

| Identidad | Fórmula | |-----------|----------| | Pitagórica | ( \sin^2 x + \cos^2 x = 1 ) | | Ángulo doble seno | ( \sin 2x = 2\sin x \cos x ) | | Ángulo doble coseno | ( \cos 2x = \cos^2 x - \sin^2 x ) ( = 1 - 2\sin^2 x ) ( = 2\cos^2 x - 1 ) | | Tangente | ( \tan x = \frac\sin x\cos x ) | | Secundaria | ( 1 + \tan^2 x = \sec^2 x ) | : Let (t = \sin x)

$$2\sin x = 1$$ $$\sin x = \frac12$$

Úsalas para cambiar la forma de la ecuación y simplificarla. : Identity: (\sin 2x = 2\sin x \cos x)

: Identity: (\sin 2x = 2\sin x \cos x). So (2\sin x \cos x - \sin x = 0 \Rightarrow \sin x (2\cos x - 1) = 0). It's an excellent supplement to your classroom teaching,

I highly recommend this resource to any 1st year baccalaureate student struggling with trigonometric equations. It's an excellent supplement to your classroom teaching, and it will help you build a strong foundation in trigonometry.
