直角三角函数公式 正弦:sina=a/c (即角a的对边比斜边)。 余弦:cosa=b/c (即角a的邻边比斜边)。 正切:tana=a/b (即角a的对边比邻边)。 余切:cota=b/a (即角a的邻边比对边)。 正割:seca=c/b (即角a. 定义表达式 1/5 分步阅读 直角三角函数的定义: 正弦(sin)等于对边比斜边;sina=a/c ; 余弦(cos)等于邻边比斜边;cosa=b/c ; 正切(tan)等于对边比邻边;tana=a/b ; 余. 其它功能例如 markdown、反链、数据库、ai 等等,各家都有而且都差不多,是太微(tiddlywiki)、tana、 obsidian、logseq 、notion、flowus、affine 都有的功能,就谈不上融.

虚阅tana=对边/邻边。 在直角坐标系中相当于直线的斜率k。 扩展资料: an a=sin a/cos a tanα=1/cotα 1、设α为任意角,终边相同败喝的角的同一三角函数的值相等:tan(2kπ+α)=tanα 2、.
