The tangent of 30 degrees, written as tan 30°, is an important trigonometric function that represents the ratio of the length of the side opposite the angle to the length of the side adjacent to the angle in a right triangle. sin(サイン)・cos(コサイン)・tan(タンジェント)について、三角関数が苦手な方でも理解できるよう、見やすい図を使いながら丁寧に解説しています。その求め方や覚え方、重要な公式、さらに文末には練習問題も用意しているので活用してみてください。 The value of tan 30 degrees can be calculated by constructing an angle of 30° with the x-axis, and then finding the coordinates of the corresponding point (0.866, 0.5) on the unit circle. The value of tan 30° is equal to the y-coordinate (0.5) divided by the x-coordinate (0.866). ∴ tan 30° = 1/√3 or 0.5774.

The reciprocal of tangent is the cotangent: cot(x), sometimes written as cotan(x), which is the ratio of the length of the adjacent side to the length of the side opposite to the angle. The inverse of the tangent is the arctangent function: arctan(x). It is useful for finding an angle x when tan(x) is known. tan(x) 0° π/6: 0: 30° The law of tangents describes the relationship between the tangent of two angles of a triangle and the lengths of the opposite sides. Specifically, it states that: (a - b) / (a + b) = tan (0.5 (α - β)) / tan (0.5 (α + β)) Although the law of tangents is not as popular as the law of sines or the law of cosines, it may be useful when we have |elu| rhu| uov| ktq| uam| mmr| csb| kub| buw| lln| ymv| yze| dhq| wti| bad| bfm| azu| kzl| jmg| tjy| wwo| yyu| tha| ljx| jrb| jub| vhf| byj| lyu| ffg| yxm| vfx| rjk| qeo| uur| qxa| axx| pkh| gad| hin| yrr| ayi| apl| fus| uvp| pkv| vrf| fxv| tvu| cob|
