餘切 （英語： Cotangent，一般記作 ，或者ctg）是 三角函数 的一种，是 正切 的餘角函數。 它的 定义域 是整个不等于 （180°k）的实数的集合， 为整数， 值域 是整个实数集。 它是 周期函数，其最小正周期为 （180°）。 餘切函数是 奇函数。 餘切函數在各个小区间上单独看為 单调递减 函數，和 正切 互為 倒數，其 函數圖形 和 正切 函數圖形 對稱 於 （45°）；該函數不連續，有 奇點 （180°k），其中 是一個 整數。 余切最早用符号tan.com表示 [來源請求]，该符号同正切一 …

Cotangent is one of the 6 trigonometric functions. It is usually referred to as "cot". Just like other trigonometric ratios, the cotangent formula is also defined as the ratio of the sides of a right-angled triangle. The cot x formula is equal to the ratio …

In a right triangle, the cotangent of an angle is the length of the adjacent side divided by the length of the opposite side. In a formula, it is abbreviated to just 'cot'. Of the six possible trigonometric functions, cotangent, secant, and cosecant, are rarely used.

3 天之前 · cotangent, one of the six trigonometric functions, which, in a right triangle ABC, for an angle A, is cot A = length of side adjacent to angle A/ length of side opposite angle A. The other five trigonometric functions are sine (sin), cosine (cos), secant (sec), cosecant (csc), and …

2024年1月24日 · We write cotangent function as “cot”. Now, the cotangent formula for the angle θ is, cot θ = (Adjacent side)/ (Opposite side) The cotangent function is positive in the first and third quadrants and negative in the second and fourth quadrants.

Typically, the cotangent space is defined as the dual space of the tangent space at "x", although there are more direct definitions (see below). One of them is closely related to propagation of …

3 天之前 · The cotangent function is the function defined by. where is the tangent. The cotangent is implemented in the Wolfram Language as Cot [z]. The notations (Erdélyi et al. 1981, p. 7; Jeffrey 2000, p. 111) and (Gradshteyn and Ryzhik 2000, p. xxix) are sometimes used in place of .

cotangent，英语单词，主要用作名词，作名词时译为“ [数] 余切；交易延期费”。
