Hello
Please help me out with the question.
Given two unit vectors A,B and their sum (vector C) which is also a unit vector, find the angle between B and C?
Thanks in advance
When working with vectors, you usually compute the angle by
$\displaystyle
cos \theta = \frac {\vec A \cdot \vec B}
{ A B }
$
where the denominators refer to the magnitude of the vectors.
In this case, since C = A + B is also a unit vector, are you working with an equilateral triangle?
