Vectors and angle

  1. Oct 7, 2004 #1
    vectors and angle....

    How can I find the angle that a vector makes with the X, Y, or Z axis?

    Example: V=24i + 12j - 20k. What angle does this vector make with x, y, and z axis?

    How do you find the angle between two vectors in general?

    Do i use inverse cosine?

    Ox : (1,0,0)
    Oy : (0,1,0)
    Oz : (0,0,1)
    V : (24,12,-20)
    "Do i use inverse cosine?"
    If you don't, you should use a calculator to help you find the angle, its faster. I do it all the time.
