Sometimes you may here the unit vector called a direction vector, because all it really does is tell you what direction the object is going in. Once we have the unit vector, or direction, we can multiply it by the magnitude to describe the ... WebThere are two formulas to find the angle between two vectors: one in terms of dot product and the other in terms of the cross product. But the most commonly used formula to find the angle between the vectors involves the dot product (let us see what is the problem with the cross product in the next section). nesa accreditation contact number
