# Angle Between Two Vectors Calculator

The sides and angles of a triangle are related with the sine law. Consider two vectors, F_{1} and F_{2}. The resultant vector produced by them is F_{R}. Hence an angle is formed between the input vector and resultant vector. In this calculator, the sine rule is used to find the angle between two vectors (F1) and (F_{R}).
