1. Calculate the angle between two position vectors.

A벡터 = (4.00,2.00,5.00)cm, B벡터 = (4.50,4.00,3.00)cm, C벡터 = (-4.50, -2.00, 1.00)cm

a) What is the length of vectors and B?

b) What is the angle between two position vectors, A and B?

c) What the angle between two position vectors, A and C?

d) What is the inner product result between A and B?

e) What is the vector sum of all three vectors?
