Thus, the cosine of angle α in a righttriangleis equal to the adjacent side’s length divided by the hypotenuse. To find the ratio of cosine, simply enter the length of the adjacent and hypotenuse and simplify. For example, let’s calculate the cosine of angle α in a triangle with th...
The Trigonometric ratios table helps you to find the values of trigonometric standard angles 0°, 30°, 45°, 60° and 90°. The values of the angle are important for solving various trignometry problems. In mathematics, the trignometric functions relates the angles of a triangle to the len...
简单来说,sin就是直角三角形中角A的正对边长度除以斜边长度。 - 例句:在直角三角形中,sin A 等于对边长度除以斜边长度。(In a right triangle, sin A is equal to the length of the opposite side divided by the hypotenuse.) 2. cos(余弦) - 英文表达:cosine - 发音:英[kəʊ'saɪn],美[k...
