sorry again. How do i make the last one to the dot product equation? the vector G is not a number now but set of coordinates . again sorry but i am a novice and i need full explanation from start to end thank you, youre a life saver the dude

thank you!but.. it is for excel chart. i don't know how to make the vectors for the equation when i use cartesian coordinate. i mean how do i make the vector G from A(Ax,Ay) and B(Bx,By) can someone write it down for me. thank you !

I have some question guys i have four points in the x,y plane in cartesian coordinates. A (Ax,Ay) B(Bx,By) C(Cx,Cy) D(Dx,Dy) A and B is vector G C and D is vector F I would like to know what is the equation to get the angle between those two vectors (G,F) . and what are the...
