Fundamentally, he developed an equivalence relation on the pairs of points in the plane, and so created the first set of vectors in the plane. Here are a few vectors joining two points problems: Find the vector and its magnitude, which joins the point A (4, 5, 6) to point B (10, 11, 12). Now, choose the vector representation (by Coordinates or Terminal points) from the drop-down list. To find the angle $ \alpha $ between vectors $ \vec{a} $ and $ \vec{b} $, we use the following formula: Note that $ \vec{a} \cdot \vec{b} $ is a dot product while $\|\vec{a}\|$ and $\|\vec{b}\|$ are magnitudes of vectors $ \vec{a} $ and $ \vec{b}$. Find the formula analogically to the 2D version: $$angle = cos^{-1}{[(xn xm) * (xp xo) + (yn ym) * (yp yo) + (zn zm) * (zp zo)] / [\sqrt{((xm xn)^2 + (yn ym)^2+ (zn zm)^2)} * \sqrt{((xp xo)^2 + (yp yo)^2 + (zp zo)^2)}]}$$.
