Sin 20°. 2nd PUC Basic Maths Compound Angles, Multiple Angles, Sub Multiples Angles and Transformation Formulae Two Marks Questions and Answers. Question 1. P.T Cos (A + B). Cos (A – B) = Cos 2 A – Sin 2 B. Answer: L.H.S = Cos (A + B). Cos (A – B) = (Cos A. Cos B – sin A. Sin B) (Cos A. Cos B + Sin A Sin B) Feb 27, 2019 · For cos For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90° Cos is the opposite of sin. We should learn it like cos 0° = sin 90° = 1 cos 30° = sin 60° = √3/2 cos 45° = sin 45° = 1/√2 cos 60° = sin 30° = 1/2 cos 90° = sin 0° = 0 So, for cos, it will be like 1, √3/2, 1/√2, 1/2, 0 For tan If cos (α + ) =4/5 and sin (α- )=5/13 , where α lie between 0 and π/4, then find the value of tan 2α. asked Feb 17, 2018 in Class XI Maths by nikita74 ( -1,017 points) trigonometric functions Oct 23, 2010 · Students who complete a COS admission application and counseling appointment are eligible for priority registration for Summer/Fall 2021 classes.

O cosseno é uma função par , o que quer dizer , que dentro do argumento dela $$\cos 120\degree=\cos\frac{2\pi}{3}=\frac{(-1)\cdot\text{Cateto adyacente}}{\text{Hipotenusa}}=-\frac{1}{2}$$ Es decir, el coseno de 120 grados o 2π/3 radianes es igual a menos uno partido por dos. Por simetría puede deducirse que el coseno de 120° es exactamente igual al coseno de 240°. Puedes ver esta igualdad representada en el The values of sin, cos, tan, cot at the angles of 0°, 30°, 60°, 90°, 120°, 135°, 150°, 180°, 210°, 225°, 240°, 270°, 300°, 315°, 330°, 360° cos(x) Extended Keyboard; Upload; Examples; Random; Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.
