convert cosine to angle

C language cos () function: Cosine valueheader file: #include The Cos () function is used to find the cosine value, that is, the ratio of the side length of the angle to the length of the hypotenuse, and the prototype is:

Recently learned some about three-dimensional space rotation related knowledge, to comb the memo.The rotation of the three-dimensional space (3D Rotation) is a very magical thing: if a rigid body in three-dimensional space for any rotation, as long
