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 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).
