The Angle Between Two Vectors A physical quantity that possesses a magnitude and a fixed direction is called a vector quantity. And a quantity that has the only magnitude is called a scalar quantity. The standard representation of a vector in the three-dimensional space ...
This example shows how you can find the angle between two vectors. The program has three main parts: selecting the points that define the vectors, drawing the vectors, and calculating the angle between them. The last task is the most important, but they're all interesting so I'll cover ...
