请问tan tan x，arc tan（tan x），tan（arc tan x）都是怎么算出来的？ 请问tan tan x，arc tan（tan x），tan（arc tan x）都是怎么算出来的呀？ 详细步骤是怎样的？ 以及为什么 显示全部 关注者 15 被浏览 对于单词sine, cosine, tangent, cotangent, secant, cosecant的由来，这里不讨论，这里讨论的是为什么这些三角函数会有如此中文名称。 首先，先看诱导公式五 \sin\left (\frac {\pi} {2}-x\right)=\cos x\\ \tan\left (\frac {\pi} {2}-x\right)=\cot x\\ \sec\left (\frac {\pi} {2}-x\right)=\csc x\\ 然后再重新叙述一遍初中时学过的余角的定义. 若正切值大于1，可以先取倒数算出tan (π/2-y)，之后按照上述方法求出对应角度，最后记得变换回原角度即可。 上述是我能想到的相对最简便的手动估计反正切函数的方法。 知乎，中文互联网高质量的问答社区和创作者聚集的原创内容平台，于 2011 年 1 月正式上线，以「让人们更好的分享知识、经验和见解，找到自己的解答」为品牌使命。知乎凭借认真、专业、友善的社区氛围、独特的产品机制以及结构化和易获得的优质内容，聚集了中文互联网科技、商业、影视. 但是由于∠A＝90°，∠B就永远≠90°，只能说越来越接近，而随着x越来越大，这个tan值就会越来越大 我们来想象一下这个极限的情况 看一眼俄罗斯wiki上的一个说明吧： В западной литературе тангенс, котангенс и косеканс обозначаются {\displaystyle \tan x,\cot x,\csc x} Тригонометрические функции 发布于 2016-10-03 13:44 知乎用户 6 人赞同了该回答
为什么计算器上的tan-1次方和实际上1/tan结果不一样？ 如图，具体来说是编程语言理解的问题吗 [图片] [图片] [图片] [图片] 还有sin (arctanx)，tan (arcsinx)， arcsin (tanx)，arctan (sinx)。 十年缺项日经题天天出现，勿随意代值。 少用局部等价无穷小断章取义，哎呦喂。 泰勒公式天下第一要保证精确度适当唉。 重要极限千篇一律取对数LNX。 。 否则所有1^∞型都得1就太**无聊了。 sin是 正弦 sine的简写（也没简化多少），读作 [sain]； cos是 余弦 cosine的简写，读作 [ˈkəʊsaɪn]； tan是 正切 （实际是切线）tangent的简写，读作 [ˈtændʒənt]；（很多中学老师读作“滩金替”） cot是 余切 cotangent的简写，读作 [kəʊ'tændʒənt]。 注意co-前缀表示“相对”的意思，所以有“正”的，就有.
