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 ...
The equation for finding the angle between two vectors(θ ) states that the dot product of the two vectorsequals the product of the magnitudes of the vectors and the cosine of the angle between them. ( u⋅ v=|u||v|cos(θ )) Solve the equation for ( θ ). (θ =arc...
