      Calculating the angle between two vectors involves using the dot product formula. The dot product of two vectors a and b is given by a·b = |a| |b| cos(θ), where |a| and |b| are the magnitudes of the vectors, and θ is the angle between them. By rearranging this formula, we can solve for θ: θ = arccos((a·b) / (|a| |b|)).

          To simplify the process, you can use the following steps:

          To calculate the angle between two 3D vectors, you can use the formula: θ = arccos((a·b) / (|a| |b|)), where a·b is the dot product of the two vectors.
