Vectors in Space

In mathland, we had reviewed the concept of vectors, but with a twist. With vectors in space, there are three numbers to denote the vector due to the the ammount of directions it goes. A vector can be written as <V1, V2, V3>. This means that there are three axes in all, the x, the y, and the z. One can obtain the component form of a vector by subtracting the values of the coordinates of the starting point by the values of the coordinates of the terminal point. All in all, vectors in space are just normal vectors with one more direction/value. One can use the normal equations for vectors on a plane with the addition of the third value into the equation according to how the Xs and Ys are presented in the equation. These equations include the vector length, unit vector, vector addition, and etc.
