WebUn engranaje es un tipo de mecanismo que tiene dos o más ruedas dentadas, que se utiliza para transmitir potencia mecánica de un componente a otro. [1] [2] Si las dos ruedas son de distinto tamaño, la mayor se denomina corona y la menor piñón. [3] Un engranaje sirve para transmitir movimiento circular mediante el contacto de ruedas dentadas. WebLet us use the sin cos formula cos 2 θ + sin 2 θ = 1. Rewriting, we get cos 2 θ = 1 - sin 2 θ = 1- (9/25) cos 2 θ = 16/25 cos θ = 4/5 sin2θ = 2 sin θ cos θ = 2 × (3/5) × (4/5) = 24/25 Answer: sin2θ = 24/25 Example 3: Prov e (cos 4a - cos 2a)/ (sin 4a + sin 2a) = -tan a. Web10 okt. 2016 · Please see the explanation for the process. Explanation: Start with the identity for the cosine of the difference of two angles: cos( π 2 − θ) = cos( π 2)cos(θ) +sin( π 2)sin(θ) Use cos( π 2) = 0 and sin( π 2) = 1 to simplify: cos( π 2 − θ) = sin(θ) Substitute √1 − cos²(θ) for sin(θ): cos( π 2 − θ) = √1 − cos²(θ) Substitute 1 6 for cos(θ): barn ikea
