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 vectors normal to planes (1) and (2) are(n_1)=++⇒ (n_2)=The angle between the planes is defined by the angle between their normals, so the angle between (1) and (2) isθ =cos^(-1)(((n_1)⋅(n_2))( ((n_1)) ((n_2)) )))=cos^(-1)(((++)⋅)(√(1...
