    How do you determine if 2 vectors (3-D) are perpendicular just from looking at its co-ordinates or dot product?
    I have co-ordinates, Vector A = (-1,3,4) and Vector B = (1,3,-2). Help is much appreciated.

    i think you use dot product rule and then the sum of the dot product should equal 0
