Angle Between Two Vectors Calculator

The sides and angles of a triangle are related with the sine law. Consider two vectors, F1 and F2. The resultant vector produced by them is FR. 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 (FR).
