cos是余弦值，余弦值=邻边÷斜边。因为在三角形中，30°所对的直角边是斜边的一半。所以这个三角形的三边之比=1：√3：2。 扩展资料： 同角三角函数的基本关系式. 倒数关系：tanα ·cotα=1、sinα ·cscα=1、cosα ·secα=1；
Now, we will fill all the cos values. All the cos values are filled in opposite order starting from sin 0 to sin 90. I mean to say that. sin 0 = cos 90. sin 30 = cos 60. sin 45 = cos 45. sin60 = cos 30. sin 90 = cos 0. Hence, all the cos values can be filled now. We know that tan = (sin )/(cos ) Hence, all the tan values can be obtained from
