3.5: Trigonometric Functions Reference Evans 6.1 Consider a right-angled triangle with angle θ and side lengths x, y and h as shown: θ x y h The trigonometric functions sine, cosine and tangent of θ are defined as: sinθ = opposite hypotenuse = y h, cosθ = adjacent hypotenuse = x h tanθ = opposite adjacent = y x = sinθ cosθ 71
angle is oriented from the ray containing the first point 𝑩𝑩) to the ray containing the third (point (𝑨𝑨). Customarily, angles (often identified with their measures) are denoted by Greek letters such as 𝜶𝜶,𝜷𝜷,𝜸𝜸,𝜽𝜽, etc. An angle formed by rotating a ray counterclockwise (in short, ccw) exactly one complete
a the angle, in radians, subtended by PQ at O, b the area of sector OPQ. 11 A 11.6 cm O 1.4c B The diagram shows a circle of radius 11.6 cm, centre O. The arc of the circle AB subtends an angle of 1.4 radians at O. Find, to 3 significant figures, a the perimeter of the minor sector OAB, b the perimeter of the major sector OAB,
