Practical lab: Computer Graphics Sheet 2: Chapter 2: Mathematical Foundation for Graphics Practice 1. Write a program that reads two vectors and calculate the angle in radius between these two vectors (Ref: slide 47). Example: 14,5) (3.7) 0 = cos' -12 + 35 = cos = 1.079 radius Tylly, 158141 23 cos = cos 0.472 = 61,86 48.765 Note : -Use math library -Read the head file: math.h - acos(x): function returns the Inverse Cosine (cos-1) of the elements of x. Output: Emai enter the array's lents Number Enter the First Vector elements Jement 1 lement 2 Enter the Second Vector elements Element Element 2 the angle in raduis between the two vectors is: 1.07963
